In recent years, China's cancer situation is becoming increasingly serious, Xuanwu Hospital cancer treatment center director Xiuyi reminded to be alert to "air out of the disease was" always ranks first in recent years because of lung cancer incidence rate.
Xiuyi noted that air pollution is caused by lung cancer risk, but not the only factor. Chest diseases, including lung cancer, and five gas related, first, air pollution; well brought-hand tobacco smoke, secondhand smoke, third-hand smoke, fumes caused by cooking, interior decoration brings indoor air pollution; addition There is also a gas easily overlooked, is angry. If the five gas-ridden, high lung cancer is easy.
He also stressed that "due to the lung cancer early symptoms are mild, mostly hidden, early detection is not easy to be 80% of lung cancer patients in the clinical diagnosis is already in the late shift has occurred, lost the best opportunity for radical treatment."
Cancer early detection and early treatment to improve patient survival is significant. 307 Hospital of PLA Army lung oncology high alert, if there is cough, sputum, fever, headache, etc., especially long-term smokers, there is a family history of lung cancer, occupational exposure and other high-risk groups, should be checked regularly. Low-dose spiral CT can be found earlier abnormal lung lesions, but harmless. Experts also stressed that, as a strong complement histopathological and radiological examination, the new tumor markers gastrin-releasing peptide precursor using serum and plasma samples tested, can also help clear for patients with lung cancer, treatment options.
Early detection of cervical cancer can be prevented
Cervical younger trend in recent years is obvious. Beijing Union Medical College Hospital and a professor of obstetrics and gynecology Lang Jing pointed out that in the 1980s, cervical cancer patients less than 35 years to less than 5%. Today this ratio is 34%. Almost all cervical cancer is the human papilloma virus (HPV) caused. Most HPV infections have no symptoms, can be the body's immune system clears. However, in the absence of symptoms of HPV may be the case in humans lurking decade or even longer. And when the body symptoms, the cancer has entered the late stage, difficult to treat. The early detection and treatment, the majority of cervical cancer is preventable.
Therefore, experts recommend women aged 30-65 for HPV testing. The most common method for detecting cervical cancer is the Pap smear. In Ditan Hospital , Chaoyang Hospital , Peking University First Hospital , but also for a more objective detection of high-risk HPVDNA assess whether cervical precancerous lesions. Cervical precancerous lesions up to 98% cure rate.
Pay attention to precancerous colon cancer prevention
Colorectal colorectal cancer is one of the world's most common cancer, the incidence rate in the first three malignancies. Peking University Cancer Hospital, Professor Gu Jin pointed out that colorectal colorectal cancer is currently the trend is clearly younger, active treatment of precancerous lesions, such as polyps, adenomas, and some chronic bowel disease (such as chronic ulcerative colitis) and so on. Because of these factors, like family history, can lead to an increased risk of colorectal cancer.
Therefore, regular screening is necessary. Experts point out that the significance of screening is to find precancerous lesions. Research data show that 10 million people do to each check, usually will find more than 600 early precancerous lesions. If you do not timely intervention, these people will be cancerous. Experts also warned that the high incidence of colorectal cancer and related to changes in people's diet, and reducing high-fat, high protein intake may reduce the incidence of colorectal cancer.
Radiotherapy is not a scourge
Peking University Cancer Hospital, ZHU Ying, director of introduction, radiotherapy is globally recognized as one of the effective means of treating cancer. Compared to Western countries, China only a few patients have the opportunity to receive radiation therapy. There are three reasons: First, the lack of domestic radiotherapy machines per million population, only one radiotherapy machine, while the World Health Organization recommends per million population should be equipped with 3-4 sets of radiotherapy machines. Second, many cancer patients for radiotherapy do not understand, as some patients do not know that radiotherapy is a method of treatment or diagnosis. Third, some patients for radiotherapy remains misconception that does not work, or side effects. Some patients do not know at what time of radiotherapy.
In fact, with the development of radiation technology now can focus rays of local tumors, targeted and targeted, so not only can reduce the number of radiation, and reduced side effects, improved quality of life.
Ying, ZHU that, in addition to lung cancer, prostate cancer, nasopharyngeal cancer, laryngeal cancer, esophageal on early stage cancer, radiation therapy can achieve better results. For breast cancer, radiotherapy can reduce the recurrence rate.
