symptoms of cancer

Camilla Krakstad

A Cancer is a term used to describe a group of diseases characterised by abnormal cell proliferation that has the potential to infiltrate or spread to other parts of the body. Benign tumours, on the other hand, do not spread. A lump, unusual bleeding, a persistent cough, unexplained weight loss, and a change in bowel movements are all possible indications and symptoms. While these signs and symptoms may suggest cancer, they could also signal something else. Tobacco usage is responsible for approximately 22% of cancer fatalities. Obesity, poor diet, lack of physical activity, and excessive alcohol use account for the remaining 10%. Other concerns include infections, ionising radiation exposure, and exposure to contaminants in the environment. Infections such as Helicobacter pylori, hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus, and human immunodeficiency virus cause 15% of malignancies in the poor world (HIV).
