Lung cancer is a condition wherein the cells divide in the lungs
uncontrollably. These cells accumulate and form a tumor and these tumors reduce
the person’s ability to breathe. The body is programmed in such a way that the
cells die after a certain stage in their life cycle to avoid overgrowth. But
cancers cause these cells to grow and multiply when they should not. Let’s see
here about lung cancer.
Lung cancer symptoms are found in advanced stages only and they are:
while you Cough
- Shortness of
- You get a
cough which does not go away
- Chest pain
- Losing weight
- Bone pain
If the signs or symptoms persist, then you should consult the Cancer specialist in India.
The causes of lung cancer are as
- Exposure to secondhand smoke
- Exposure to radon gas
- Exposure to asbestos and other carcinogens
- Family history
- Prior history of lung cancer
- Lung disease
- Air pollution
- Exposure to diesel exhaust
Based on their appearance, the lung cancer is divided into two types
and they are:
- Small cell lung cancer: Heavy
smokers get affected by these types of cancers and are less common when
compared to non-small cell lung cancer.
- Non-small cell lung cancer: These are of different types which have
similar behavior and are grouped under this type of cancer. Some of them are
squamous cell carcinoma, large cell carcinoma and adenocarcinoma.
The staging of cancer indicates its severity and how far it has spread
through the body. This helps in deciding the course of treatment. Staging for
lung cancer is extremely complex and extensive with many sub-groups within each
stage. cell lung cancer has the
- Hidden or Occult: This will
not show on imaging scans but cancerous cells might appear in the mucus or
phlegm and might have spread to other body parts.
- Stage 0: These cells are found in the top layers of
cells which lines the airways.
- Stage I: A tumor of under5 cm
has developed in the lung but has not spread to other body parts.
- Stage II: The tumor is either 5
cm or 7 cm and has spread to other lymph nodes and in some cases to nearby
tissues but not to the lymph nodes.
- Stage III: Cancer has spread to
lymph nodes and to other parts of the lung and surrounding area.
- Stave IV: Cancer has spread to
distant body parts such as bones or brain.
Small cell lung cancer categories are limited and extensive based on
whether cancer has spread within or outside the lungs.
Lung Cancer Treatment in India
is based on the stage and
location along with the overall health of the individual. The treatments
- Radiation Therapy
- Targeted Therapy
A team of medical experts such as surgeons, radiation
oncologists, a specialist in lung treatment called pulmonologists and pulmonary
therapists work together in treating the patient.
