IS CANCER ACQUIRED OR INHERITED?
It is both.
We divide the diseases afflicting man as infective like HIV, Tuberculosis, etc.
Congenital (seen mostly in kids) like Hirschsprung's, cystic fibrosis, congenital heart diseases, etc.
Inherited or genetic like orthopedic deformities, endocrine disorders (sometimes), colonic polyps (large bowel disease) or some cancers like lung cancer, etc.
Hence, cancer is mostly acquired.
We are all aware that tobacco either in smoke form or chewable form (Gutka, Tambaaku, etc.,) can cause lung cancer, throat cancer, tongue cancer, cheek cancer, etc.
Even passive smoking can lead to lung cancer.
Oncologists firmly believe that cancer in humans is a lifestyle disease like diabetes, hypertension or metabolic syndrome.
Obesity too is a proved pre-cancerous agent or an established risk factor for some cancers including breast, large bowel, pancreas, ovarian cancers—only to name a few.
Apart from avoiding known carcinogens (cancer causing agents), one has to adopt a healthy lifestyle to maintain an acceptable BMI (Body Mass Index) to “minimize” the risk of developing cancer in one's lifetime.
