About the Oncological Society of Bengal
The Oncological Society of Bengal (OSB) is a professional association dedicated to uniting all disciplines of oncology in Surgical, Medical, and Radiation.
Established in 2014, OSB serves as a platform for oncologists across West Bengal to collaborate, exchange expertise, and promote excellence in cancer care, research, and education.
Our mission is to strengthen the oncology community through shared knowledge, continuous learning, and collective advancement in the fight against cancer.
Our Journey
Building a Strong Foundation in Cancer Care
Cancer treatment in Kolkata began decades ago, led by government hospitals and a few private centers. While Radiation Oncology developed steadily, Surgical Oncology gained prominence through dedicated efforts at Chittaranjan Cancer Hospital and other institutes.
The need for a common forum led to the formation of OSB after the 1st Indian Cancer Congress (2013) in New Delhi.
Under the leadership of Dr. A. P. Majumdar and Dr. Prabir Bijoy Kar, the society was officially registered in 2014 to unify oncologists and foster collaboration.

Major Causes of Cancer
Smoking
Smoking is by far the biggest preventable cause of cancer. Thanks to years of research, the links between smoking and cancer are now very clear. Smoking accounts for more than 1 in 4 UK cancer deaths, and nearly a fifth of all cancer cases.
SMOKING AND DRINKING TOGETHER
When you drink alcohol, cancer-causing chemicals are formed. Alcohol also affects hormone levels and makes cells even more likely to be damaged by smoking.There are lots of simple ways to cut down on alcohol.
DRY/TINNED FISH
Aim to eat oily fish two to three times a week. These fish are high in protein and omega-3 fatty acids: cod, sablefish, salmon, mackerel, sardines, and anchovies. Smaller fish (i.e. sardines, mackerel, and anchovies) causes cancer.
Air Pollution
It has classified outdoor air pollution as a cancer-causing agent (carcinogen). It is evaluated that outdoor air pollution causes lung cancer and is also linked to an increased risk for bladder cancer & other different type of cancers.
