Lung cancer treatment in pune

Smoking poisons almost every part of our body from our lungs to our heart though it doesn’t only affect a smoker. Passive or secondhand exposure to smoke can cause serious and chronic illnesses like asthma, stroke, cancer, coronary heart disease, and sudden infant death syndrome. The leading cause of lung cancer risk is cigarette smoking. According to the CDC, in the US alone, around 400 infants and 41,000 adults die each year from secondhand smoking.


Cancer is a disease caused by carcinogens like tobacco. It leads to abnormal cell growth and metabolism rates causing lumps or outgrowths that could be benign or malignant. Cancer cells, unlike our normal cells, lose their contact inhibition and can metastasize. Some of our cells have the ability to kill cancer cells but smoking reduces the body’s immunity and thus prevents this activity

Lung cancer

Lung cancer is a type of cancer that starts in the lungs and may later spread and form colonies called metastases in lymph nodes and distant organs. it can be of two types- adenocarcinoma and squamous cell carcinoma. Screening for the two types involves different processes.


Symptoms of this cancer can be very vague and ambiguous. Sometimes symptoms arise in parts of the body where there are metastases and other times patients report an overall feeling of being sick. Identifiable symptoms usually do not appear until the cancer becomes advanced. Some telltale signs of lung cancer are wheezing, shortness of breath, coughing up blood, etc. Always look out for these symptoms and never neglect them.

Prevention of Lung Cancer

There are ways to reduce the risk of developing the disease like quitting cigarettes, avoiding passive smoke, getting your surroundings tested for radon, and maintaining high safety standards in workplaces where there are chances of exposure to carcinogens.
