cancerNot AvailableNot AvailableCancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. There are over 100 types of cancers affect humans. The risk of developing certain cancers can be reduced by not smoking, maintaining a healthy weight, not drinking too much alcohol, eating plenty of vegetables, fruits and whole grains, vaccination against certain infectious diseases, not eating too much processed and red meat and avoiding too much sunlight exposure. Cancer is often treated with some combination of radiation therapy, surgery, chemotherapy and targeted therapy. The majority of cancers, some 90–95% of cases, are due to genetic mutations from environmental and lifestyle factors. The remaining 5–10% are due to inherited genetics.PMC9572478
liver cancerNot AvailableNot AvailableLiver cancer, also known as hepatic cancer and primary hepatic cancer, is cancer that starts in the liver. Cancer which has spread from elsewhere to the liver, known as liver metastasis, is more common than that which starts in the liver. Symptoms of liver cancer may include a lump or pain in the right side below the rib cage, swelling of the abdomen, yellowish skin, easy bruising, weight loss and weakness.("Adult Primary Liver Cancer Treatment (PDQ®)–Patient Version". NCI. 6 July 2016. Archived from the original on 2 October 2016. Retrieved 29 September 2016) The leading cause of liver cancer is cirrhosis due to hepatitis B, hepatitis C or alcohol.(PMID: 25530442) The most common types of liver cancer are hepatocellular carcinoma (HCC), which makes up 80% of cases, and cholangiocarcinoma.(World Cancer Report 2014.
