What are the symptoms of cancer
summary
Generally speaking, cancer mainly takes the form of tumor. We often say that cancer in most cases refers to malignant tumors. Cancer is caused by abnormal regulation of normal cell proliferation. Cancer cell is the smallest unit of cancer. It can not only replicate and proliferate uncontrollably, but also invade other normal body tissues, causing more serious consequences. What are the symptoms of cancer? Let's talk about it
What are the symptoms of cancer
Recurrence of lung or chest cancer is easy to cause some respiratory symptoms. For example, patients with lung cancer may cough for a long time, sometimes feel chest pain, and some lung cancer patients may cough bloody sputum.
A friend with cancer will not only lose weight, but also have a serious impact on his appetite. For example, the appetite of patients with gastric cancer will drop to the lowest point, and even some people with gastric cancer have not eaten for several days. Some breast cancer can cause the nipple to flow out of liquid without any reason, and also make the breast grow lumps.
Many times we see that people with cancer will be very thin, which is a typical symptom of cancer. Cancer can not only make people thin, but also make people feel weak. Some cancers may occur in the abdomen, where the patient may feel abdominal pain.
matters needing attention
Primary prevention is to eliminate or reduce the possible carcinogenic factors and prevent the occurrence of cancer. About 80% of cancers are related to environment and living habits. Improving living habits, such as quitting smoking, limiting drinking, diversifying food, eating less pickled food, controlling weight, exercising properly, paying attention to environmental protection, identifying carcinogens and cancer promoters in the environment, and strengthening occupational protection, are more important cancer prevention measures. In recent years, both immunoprophylaxis and chemoprophylaxis belong to primary prevention, such as mass vaccination of hepatitis B vaccine and chemoprophylaxis of colorectal adenoma with selective cyclooxygenase-2 (COX-2) inhibitors.
