The general effects of radon to the human body are caused by its radioactivity and consequent risk of radiation-induced cancer. Lung cancer is the only observed consequence of high concentration radon exposures; both human and animal studies indicate that the lung and respiratory system are the primary targets of radon daughter-induced toxicity ...
Residential exposure to radon gas has similar cancer risks as passive smoking. [6] Radiation is a more potent source of cancer when it is combined with other cancer-causing agents, such as radon gas exposure plus smoking tobacco. [6]
Oral cancer can be prevented by avoiding tobacco products, limiting alcohol use, sun protection on the lip, HPV vaccination, and avoidance of betel nut chewing. Treatments used for oral cancer can include a combination of surgery (to remove the tumor and regional lymph nodes), radiation therapy, chemotherapy, or targeted therapy. The types of ...
These clots may disrupt circulation locally or dislodge and travel to the heart, lungs, or brain, and may be fatal. Symptoms of blood clots may include pain, swelling, warmth and in late stages, numbness, particularly in the arms and legs. Some cancer treatments may further increase this risk. [10]
222 Rn decay products have been classified by the International Agency for Research on Cancer as being carcinogenic to humans, [127] and as a gas that can be inhaled, lung cancer is a particular concern for people exposed to elevated levels of radon for sustained periods.
Experimental cancer treatments are studied in clinical trials to compare the proposed treatment to the best existing treatment. Treatments that succeeded in one cancer type can be tested against other types. [258] Diagnostic tests are under development to better target the right therapies to the right patients, based on their individual biology ...
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.
Dose equivalent calculates the effect of radiation on human tissue. [4] This is done using tissue weighting factor, which takes into account how each tissue in the body has different sensitivity to radiation. [4] The effective dose is the risk of radiation averaged over the entire body. [4] Ionizing radiation is known to cause cancer in humans. [4]
