Cancer, also known as a malignant tumor or malignant neoplasm, is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. Not all tumors are cancerous; benign tumors do not spread to other parts of the body. Possible signs and symptoms include: a new lump, abnormal bleeding, a prolonged cough, unexplained weight loss, and a change in bowel movements among others. While these symptoms may indicate cancer, they may also occur due to other issues.
Many cancers can be prevented by not smoking, maintaining a healthy weight, not drinking too much alcohol, eating plenty of vegetables, fruits and whole grains, being vaccinated against certain infectious diseases, not eating too much processed and red meat, and avoiding too much exposure to sunlight.
1. Not smoking
You’ve probably been warned of this many times before, but whoever was warning you had a valid reason to. Smoking is the highest cancer risk factor that we can control. Smoking is responsible for lung cancer, and many other types of cancer. The best way to prevent cancer is to never start – or quit if you already smoke. Secondhand smoke is also a significant cancer risk factor. The smoke contains more than 60 carcinogens which disturb natural cell development and can trigger the development of cancer cells.
