Cancer is a disease characterized by the development of abnormal cells, which destroy normal body tissue. Frequently, it spreads throughout the body and it is the second-leading cause of death in the world. Recently, this has improved thanks to cancer screening and a proper cancer treatment. Even if there is a slight idea about what are some risk factors, the majority of cancers occur in people who do not have any known risk factors. These are: age, habits like smoking or drinking, and family history.
Symptoms vary depending on what part of the body is affected. The most common signs are fatigue, lumps under skin, weight or skin changes, persistent cough, difficulty breathing or swallowing, hoarseness, indigestion, unexplained muscle pain, fevers or night sweats and unexplained bleeding. To prevent cancer, it is advisable stop smoking, avoid excessive sun exposure, exercising, drinking alcohol in moderation and schedule cancer screening exams.
