Cancers

Cancer, are also known as a malignant tumor or malignant neoplasm, this is a group of diseases involving abnormal cell growth with the potential to invade and/or spread to the other parts of the body. Cancer can start anywhere in the human body which is made up of trillions of cells. Human cells grow, divide to form new cells as the body needs them in that way. When cells grow old or become damaged, they die, and new cells take their place, many cancers form solid tumors, which are the  masses of tissue. Cancers of blood, such as leukemia’s, generally do not form solid tumors. Many cancers can be prevented by avoiding smoking and maintaining a healthy weight, not drinking  much alcohol, eating plenty vegetables, fruits, whole grains, getting  vaccinated against certain infectious diseases, not eating  much processed and red meat,  avoiding  much exposure to sunlight. Systemic symptoms include unintentional weight loss, fever, excessively tired, changes to the skin. Hodgkin disease, leukemias, cancers of the liver or kidney can cause a persistent fever of unknown origin.
