Clinical manifestations of cancer
Cancer is a large class of malignant tumors collectively. The occurrence of cancer due to various parts of different pathological differences and the different stages of development, it will produce a variety of clinical manifestations. But the cancer early symptoms are often small, to be gradually developed to a certain stage after the performance of a range of symptoms and signs. Generally be divided into Bureau of cancer treatment clinical manifestations and systemic symptoms of two aspects.
1, local performance:
1, tumor: cancer formed by malignant proliferation may hand in the body surface or deep touch. Thyroid gland, parotid gland, or breast cancer may be relatively shallow parts of the skin touch. Tumor metastasis to the lymph nodes, swollen lymph nodes can lead to some superficial lymph nodes, such as the neck lymph nodes and axillary lymph easy to touch. As for the deeper parts of the body of stomach cancer, pancreatic cancer and so on, will have to be touching the pressing force. Malignant tumors, including cancer, mass rapid growth, the surface is not smooth, hard-driven; benign tumors are generally smooth surface, such as eggs and table tennis as easy as sliding.
2, pain: the emergence of cancer pain is often prompted to have entered the middle and late. Pain or a dull pain began mostly at night obviously. Then gradually increase and become unbearable, around the clock. Painkillers do not work in general. Pain is usually caused by neural invasion of cancer cells.
3, ulcer: As the surface of some fast-growing cancer, cancer, nutrition, shortage of supply, formed by tissue necrosis occurs. Such as certain breast cancer in the breast occurring at the crater-like ulcers or dish patterns, secretion bloody secretions, concurrent infection, may have bad smell. In addition, stomach cancer, colon cancer can also be the formation of ulcers, generally only by endoscopy, colonoscopy can be observed.
4, bleeding: infringe cancer tissue blood vessels or rupture of small blood vessels in carcinomas arising. Such as the lung cancer patients may be hemoptysis, sputum with blood; stomach, colon, esophageal cancer can be blood in the stool.
5, obstruction: the rapid growth of cancer tissue caused by obstruction. When the obstruction site in the respiratory tract that is raw breathing difficulties; esophageal cancer is difficulty in swallowing and esophageal obstruction; of biliary tract cancer can block parts of the common bile duct and the Health and jaundice; bladder cancer, urinary tract obstruction urination difficulties arise. In short, the site of obstruction due to cancer of the differences there are different symptoms.
6, Other: intracranial tumors can cause visual impairment (optic nerve compression), facial paralysis (compression of the facial nerve) and many other nervous system symptoms; bone tumor invasion can lead to bone fractures; liver cancer caused ascites albumin and so reduce the Er Zhi.
