Though
there are over 100 types of Cancers, the following are amenable
to quick Complementary Therapy Treatment in terms of quality of
life and symptomatic relief resulting even in regression of cancer.
Some of the important types of cancers are discussed below. However,
this is not an exhaustive list and will be updated from time to
time.
1. Bone Cancers
The cancer that begins in the bone is called primary bone cancer
sarcoma. Most often sarcomas affect the bones in the arms and
legs.
Osteosarcoma is the most common bone cancer and usually is found
in young people between the ages of 10 and 25. Osteosarcoma starts
at the end of bone when new bone is forming. Ewing's sarcoma also
is found in young patients between the ages of 10 and 25. This
type of bone cancer begins in the shaft or middle part of the
long bone.
Chondrosarcoma is primarily an adult form of bone cancer. It begins
in cartilage around the joints. Other types of bone cancer are
rare and usually affect those older than 30. These cancers can
also involve the bone but unless they begin in the bone they are
not considered primary bone cancers.
The most common symptom of bone cancer is pain. In many instances
bone cancer interferes with normal movement of the extremity and
can also cause bones to break.
Bone cancers can be diagnosed through bone scans. In a bone scan
radioactive material is injected into the blood stream, collects
in abnormal areas of the bone, and is detected under a special
scanner. CT scans and MRI scans also are used to detect sarcoma.
Biopsy is the only way to obtain a definitive diagnosis of bone
cancer. Biopsy involves sampling a piece of tissue and examining
it closely under a microscope. A pathologist can determine the
type of sarcoma and the rate of growth. These factors are important
in determining the treatment of sarcoma. Treatment of sarcomas
may involve surgery, radiation therapy, and/or chemotherapy. Surgery
is always (almost) a part of sarcoma treatment due to the risk
of recurrence at the site of origin. Unless the tumor is very
large, amputation is avoided and the limbs bearing procedures
are adopted. In the limbs bearing procedure artificial bone is
used to replace bone affected by the cancer.
Chemotherapy is another treatment for sarcoma. It may be used
prior to surgery to decrease the tumor size or after surgery to
kill any remaining tumor cells. Chemotherapy may also be used
to control growth of sarcoma that has spread to other parts of
the body. Radiation is also used to treat bone cancer locally.
It may be used before or after surgery and sometimes it is used
instead of surgery. Yoga Therapy helps in reducing pain and Improve
Quality of life in fact of all kinds patients.
2. Leukemia
Leukemias are bone marrow-or lymph tissue-derived cancers.
They are cancers that affect the immature white blood cells, red
blood cells, and platelets (blood clotting cells). Leukemia represents
about 3% of the cancer incidence in the U.S.
The majority of our blood cells are produced in the "spongy"
center of our bones. Therefore, leukemia is said to be a cancer
of the bone marrow. A small amount of cell production occurs in
our lymph nodes. Dysfunctional cell production within this tissue
can lead to lymphocytic leukemia. The word "leukemia"
originated from the Greek and means, "white blood."
The uncontrolled, overgrowth of abnormal white blood cells crowds
the healthy cells in the bone marrow. When this occurs, the abnormal
cells spill into the bloodstream. This causes an unhealthy balance
of the three blood cell types. Anemia, infection, and bleeding
can occur from this abnormal cell balance.
Anemia results from a low number of red blood cells and causes
the patient to experience fatigue, shortness of breath, and/or
dizziness. Infection occurs because the abnormal white blood cells
no longer effectively kill bacteria and viruses. Bleeding such
as nose bleeds, easy bruising, bleeding gums, and/or vaginal bleeding
occur due to a low number of platelets-cells that function to
clot the blood.
There are two major types of leukemia. Lymphocytic leukemia affects
the lymphoid white blood cells. Myelocytic (or non-lymphocytic)
affects the myeloid line of cells. Leukemia's can also occur as
acute or chronic. Acute leukemias have quicker onset and disease
course (1-5 months). Chronic leukemias have slower onset and progression
(2-5 years). The most common leukemia in children is Acute Lymphocytic
Leukemia (ALL). The two most prevalent leukemias in adults are
Acute Myelogenous (AML) and Chronic Lymphocytic Leukemia (CLL).
The treatment for leukemia is chemotherapy. If the patient is
a candidate, high dose chemotherapy and bone marrow transplant
are also possible treatment options.
3. Brain Tumors
Anatomy of the brain
The brain is composed of: The cerebrum, the largest part of the
brain, contains two cerebral hemispheres and is divided into four
lobes where discrete functions occur:
-
The frontal lobe, which controls reasoning, emotions, problem-solving,
and parts of speech and movement
- The
parietal lobe, which controls the sensations of touch, pressure,
pain, and temperature
- The
temporal lobe, which controls memory and the sense of hearing
- The
occipital lobe, which controls vision.
- The
cerebellum, or "little brain," is located beneath
the cerebrum. The cerebellum controls coordination and balance.
The brain stem, which is the lowest portion of the brain and connects
to the spinal cord, controls involuntary functions essential for
life, such as the beating of the heart and breathing.
The meninges are the membranes that surround and protect the brain
and spinal cord. There are three meningeal layers, called the
dura matter, arachnoid, and pia arachnoid.
The brain and spinal column make up the central nervous system
(CNS), where all vital functions of the body are controlled. When
tumors arise in the central nervous system, they are especially
problematic because a person's thought processes and movements
can be affected. These tumors can also be difficult to treat because
the tissues surrounding the tumor may be vital to functioning.
Brain cancers are the second most common form of childhood cancer
and the eighth most common cancer in adults.
Gliomas: A glioma is a tumor that grows from
a glial cell, which is a supportive cell in the brain. There are
two types of supportive cells: astrocytes and oligodendrocytes.
Therefore, most gliomas are called either astrocytoma or oligodendroglioma,
or a mixture of both. Gliomas are graded (how much the tumor appears
like normal brain tissue) from I to IV based on their degree of
aggressiveness. A grade I glioma is a benign tumor, while grade
II through IV are tumors with an increasing degree of aggressiveness
and are therefore considered increasingly malignant in potential.
Brain tumors represent the third and fourth most common cause
of cancer related death for 15-34-year-old males and females respectively,
with over 17,000 new cases being diagnosed. The incidence increases
with age, averaging from 17.9 to 18.7 per 100,000 individuals
between the ages of 65 and 79. There are few genetic and environmental
links to developing brain tumors. Exceptions to this include genetic
abnormality, which can result in optic nerve gliomas and other
brain tumors. Individuals with occupational exposure to pesticides,
herbicides, and fertilizers, and workers in petrochemical industries
and some health professions seem to have a higher than expected
increase in the incidence of brain tumors. Viral causes of brain
tumors have only been implicated in laboratory animals.
Types of gliomas (Brain Tumours):
There are over 100 different types of primary brain tumors. For
practical purposes, this review is divided into glioma and non-glioma
types of tumors.
-
Astrocytoma is the most common type of glioma, making up about
11% of all brain tumors. Astrocytomas begin in cells called
astrocytes in the cerebrum or cerebellum. Glioblastoma multiforme
(also called grade IV astrocytoma) is a very aggressive form
of astrocytoma.
- Oligodendroglioma
is a tumor that develops from cells called oligodendrocytes.
These cells are responsible for producing the myelin that
surrounds nerves. Oligodendrogliomas make up about 4% of all
brain tumors.
- Brain
stem gliomas begin in the glial cells in the brain stem.
- Ependymomas,
which begin in the ependyma (the cells that line the passageways
in the brain where cerebrospinal fluid is made and stored),
make up about 2% of all brain tumors.
- Mixed
tumors, which are composed of more than one of the glial cell
types, make up about 1% of all brain tumors.
- Non-glioma
tumors. Non-glioma tumors begin in other types of cells in
the central nervous system, and are described as either benign
or malignant.
- Meningioma
is the most common primary brain tumor, making up about 27%
of all brain tumors. It begins in the meninges surrounding
the brain and spinal column, and is most often benign. Meningioma
can cause significant symptoms as it grows and presses on
the brain or spinal cord.
- Acoustic
schwannoma is a rare tumor that begins in the vestibular nerve,
and is normally benign.
- Craniopharyngioma
is a benign tumor that begins near the pituitary gland. These
tumors are rare, making up less than 1% of all brain tumors.
- Medulloblastoma,
which begins in granular cells in the cerebellum, is most
common in children and is most often malignant. Medulloblastomas
make up about 2% of all brain tumors.
- Primary
CNS lymphoma is a form of lymphoma (cancer that begins in
the lymphatic system) that starts in the brain, and makes
up about 2% of all brain tumors.
- The
pineal and pituitary glands, located near the base of the
brain, are the location of about 7% of all brain tumors.
About
5% of all brain tumors cannot be assigned an exact type.
Diagnosis of brain tumors is made when a patient presents with
a new or unusual neurological symptom. Symptomatology for the
brain tumor varies, and is depend upon the areas of the brain
affected, as well as the size and degree of malignancy. Symptoms
of a brain tumor may include
-
Seizures (occurring in 20%-50% of patients);
- Headache
with or without nausea and vomiting (occurring in approximately
one-third of all patients);
- one-sided
weakness or paralysis;
- changes
in taste, vision or smell;
- dizziness;
-
loss of appetite;
- changes
in personality, mood, mental capacity, and/or concentration;
-
changes in sleep patterns; and/or slowing or psychomotor activity.
Because some of these symptoms may be confused with depression
or other psychological problems.
Diagnosis of a brain tumor is often delayed. Diagnostic testing
for brain tumors includes Computerized Tomography (CT) Scans and
more often Magnetic Resonance Imaging (MRI) Scanning. Once a brain
tumor is discovered a patient may undergo more extensive full-body
evaluation to rule out the possibility that the tumor has metastasized
(spread) from elsewhere in the body. If metastases are ruled out,
the patient is usually sent for a neurosurgical procedure to make
a definitive diagnosis.
Prognosis of patients with brain tumors varies depending upon
the size, location, and degree of malignancy of the tumor.
Grades I and II tumors may have a median survival of five to seven
years.
Grade III disease usually have a much poorer prognosis, with a
median survival of only 18 to 24 months.
Grade IV brain tumors, also known as Glioblastoma multiforme,
have the poorest prognosis; with the patient's life expectancy
averaging only 8-10 months after diagnosis. Treatment or lack
of it may alter all of these figures.
Treatment for brain tumours depends upon the size, location, and
degree of malignancy of the lesion. Patients with brain tumors
are usually initially treated with oral glucocorticoid therapy
to reduce the swelling around the tumor and improve symptoms and
function. Surgical treatment of brain tumors is often an option
with the goal being to resect the tumor completely and provide
cure. This is often not possible in patients with multiple tumors,
large sized tumors, tumors of the brain stem, and tumors with
higher grade.
In those patients, palliative radiation therapy may be combined
with chemotherapy to enhance the effectiveness of the treatment.
New research studies are underway to determine the best scheduling
of radiation therapy and to determine the optimum timing and dose
of the chemotherapy to bring about the best patient outcome.
The brain and spinal column make up the central nervous system
(CNS), where all vital functions of the body are controlled. When
tumors arise in the central nervous system, they are especially
problematic because a person's thought processes and movements
can be affected. These tumors can also be difficult to treat because
the tissues surrounding the tumor may be vital to functioning.
4.Lymphoma
Lymphoma is a term applied to any cancer that develops in lymphoid
tissue. Lymphoid tissues make up the body's lymphatic system and
play an important role in the body's defense against infection.
There are two major types of lymphomas: Hodgkin's and non-Hodgkin.
Hodgkin's lymphoma can occur at any age; however, it is seen most
frequently in young adults and is more common in males. A painless
enlarged node in the neck is the most common presenting symptom.
Other symptoms include fever, drenching night sweats, and weight
loss. Treatment for Hodgkin's lymphoma includes radiation therapy,
chemotherapy, or a combination of the two.
Treatment for non-Hodgkin's lymphoma depends on the extent of
the disease. Radiation therapy may be used for non-Hodgkin's lymphoma
confined to lymph nodes. When the stomach, small intestine, spleen,
bone marrow, liver, or skin is affected, chemotherapy is often
initiated. Sometimes, both methods of treatment are used.
5.Breast cancer
Breast cancer is the most common cancer occurring in
women (excluding cancers of the skin) and the second most common
cause of death from cancer in women, after lung cancer. Men can
also develop breast cancer, but male breast cancer is rare, accounting
for less than 1% of all breast cancer cases. If diagnosed at an
early stage, breast cancer has a hopeful cure rate - up to approximately
97% of women diagnosed with localized breast cancer will be alive
five years after their diagnosis. Even if the cancer is found
at a more advanced stage, new therapies have enabled many people
with breast cancer to live with their disease and enjoy a good
quality of life.
The
breast is comprised mainly of fatty tissue. Within this tissue
is a network of lobes, which are made up of many tiny lobules
that contain milk glands. Tiny ducts connect the glands, lobules,
and lobes and carry the milk from the lobes to the nipple, located
in the middle of the areola. Blood and lymph vessels run throughout
the breast; the blood nourishes the cells, and the lymph drains
the waste products.
About
90% of all breast cancers occur in the ducts or lobes, with almost
75% of all breast cancers beginning in the cells lining the milk
ducts. These cancers are called ductal carcinomas. Cancers that
begin in the lobes are called lobular carcinoma and are more likely
to be found in both breasts.
If
the disease has spread away from its place of origin, it is called
invasive or infiltrating ductal or lobular carcinoma. Disease
that has not spread is called in situ, meaning "in place."
The course of in situ disease, as well as its treatment, varies,
depending on its place of origin. Currently, oncologists recommend
that ductal carcinoma in situ (DCIS), which accounts for the majority
of in situ breast cancers, be surgically removed to prevent progression
to invasive disease.
Other,
less common cancers of the breast include medullary (making up
about 5% of all breast cancers), mucinous, tubular, papillary,
or inflammatory. Paget's disease is a type of cancer that can
begin in the nipple.
Breast
cancers grow at different rates, but some oncologists estimate
the average tumor doubles in size every 100 days. Since cancers
start with one irregular cell, even with this doubling time, they
may not be palpable (able to be felt) for years. Mammography can
find tumors that are too small to be felt, but even so, the tumors
have probably been growing for years before they are large enough
to be visible on a mammogram.
Breast
cancer cells migrate to the lymph nodes under the arm (axillary),
in the neck (cervical), or those just below the collarbone (supra-clavicular).
The most common sites of metastasis, or spread, of breast cancer
are skin, distant lymph nodes, bone, lung, and liver.
6.Lung Cancer
Cigarette
smoking is the main cause of Lung cancer. Anyone can develop lung
cancer. Lung cancer is always treatable, no matter the size, location,
or if the cancer has spread.
The
lungs absorb oxygen from the air and bring it into the bloodstream
for delivery to the rest of the body. As the body's cells use
oxygen, they release carbon dioxide. The bloodstream carries carbon
dioxide back to the lungs where it leaves the body when we exhale.
The
lungs contain many different types of cells. Most cells in the
lung are epithelial cells. These cells line the airways and produce
mucus, which lubricates and protects the lung. The lung also contains
nerve cells, hormone-producing cells, blood cells, and structural
or supporting cells.
There
are two major types of lung cancer. Non-small cell lung cancer
(the most common) is believed to arise from epithelial cells.
Small cell lung cancer is believed to arise from nerve cells or
hormone-producing cells. The term "small cell" refers
to the size and shape of the cancer cells seen under the microscope.
Lung
cancer begins when cells in the lung grow out of control, and
form a tumor. A lung tumor can begin anywhere in the lung. Once
a lung tumor begins to grow, it may or may not shed cancer cells.
These cells can travel through tiny tubes in the lung called lymphatic
vessels, which drain into collecting stations called lymph nodes
located in the lungs and the center of the chest. Cancer cells
can also travel through blood vessels to distant sites in the
body, where they can form other tumors. This process is known
as metastasis.
Not
all lung tumors metastasize. In general, small cell lung cancers
are more likely to metastasize than non-small cell lung cancers,
so the two types of lung cancer are treated in different ways.
The
location and size of the initial lung tumor, and whether it has
spread to nearby lymph nodes or distant sites, determines the
stage of lung cancer. The type of lung cancer (non-small cell
versus small cell) and the stage of disease determine what type
of treatment is required.
