Cancer is a leading cause of death worldwide, accounting for nearly 10 million deaths in 2020, or nearly one in six deaths. There is no doubt that cancer is one of the scariest diseases out there and usually has no cure if it develops to a certain stage. On account of National Cancer Awareness Day, let’s take out time to understand the symptoms of cancer and ways to detect it at an early stage, and also to understand what causes it so that necessary precautions can be taken.
Cancer is an umbrella term for a number of diseases or abnormalities caused by the rapid division, spread and production of abnormal cells in the body. This group of abnormal cells can divide without any control and can spread to nearby or distant organs. Cancer can begin from almost any cell in the body.
Health Shots reached out to Dr Samir Gupta, Professor and HOD, Department of Surgical Oncology, Dr DY Patil Medical Hospital and Research Centre, to understand basics about cancer.
The most common sites for cancer are breasts, uterus, lungs, colon and rectum, and prostate. The warning signs for cancer are:
* Thickening or lump in the breast.
* Unusual bleeding or discharge from the vagina
* Change in bowel habits that is persistent
* Loss of weight or appetite
* Persistent fatigue or low grade fever
These are some of the most commonly observed symptoms of cancer. If you observe any of these it is best to consult your doctor and get some cancer screenings done for early detection as at early stages of cancer the treatment is possible.
Based on the symptoms other tests like blood investigations, Chest X-ray and Ultrasound for the abdomen are done to detect cancer.

According to the World Health Organisation, around one-third of deaths from cancer are due to tobacco use, high body mass index, alcohol consumption, low fruit and vegetable intake, and lack of physical activity. It can also be caused because of genetic factors or some environmental factors like:
* Exposure to radiation and Ultraviolet (UV) light
* Harmful chemicals present in cigarettes, alcohol, air pollution or contaminated foods and drinks
* Infection caused by virus, bacteria or parasite
Now that we know what are the major causes of Cancer we can at least try our best to stay away from these things.
1. Maintain an active lifestyle. Lack of physical activity is a major cause of cancer and thus the best prevention technique will be to at least get 30 minutes of daily physical activity.
2. A person’s diet should be balanced with large portions of green leafy vegetables, fruits, whole grains, lean meat or plant based proteins. Foods rich in antioxidants are also supposed to help. “Also, the amount of carbohydrates and sugar in your diet must be restricted,” says Dr Gupta.
3. Chemical carcinogens present in tobacco and alcohol are again some of the major causes of cancer and hence one should avoid these. Dr Gupta advises that smoking should be avoided completely and only a minimum amount of alcohol should be taken.
4. Try to reduce stress in your life by regular 6-8 hours of sleep. Meditation and Yoga can also help in reducing stress.
