cancer is a group of diseases that cause cells in the body to grow and spread uncontrollably. These cells can invade and damage nearby tissues and organs. Cancer can also spread (metastasize) to other parts of the body, through the bloodstream or lymphatic system.
Cancer cells are abnormal cells that grow and divide in an uncontrolled way. They can invade and damage nearby tissues and organs, and can spread to other parts of the body. These cells are the cause of many types of cancer. Cancer cells can interfere with the normal functioning of the body by crowding out healthy cells, creating inflammation, and releasing hormones and other chemicals. They can also interfere with the body’s ability to fight infection and heal. Some types of cancer cells can even create their own blood vessels, allowing them to grow and spread rapidly.
Cancer is caused by changes in the genetic material of cells, which can be inherited or caused by environment factors, such as exposure to radiation, certain chemicals, and some viruses. The changes can cause the cell to grow and divide in an uncontrolled way, which can lead to tumors.Treatment for cancer depends on the type and stage of cancer, and can include surgery, radiation, chemotherapy, targeted therapy, and immunotherapy. Early diagnosis and treatment can improve the chances of successful treatment and survival.
