16-20 year-old female smoking is more susceptible to breast cancer

In Asia, the incidence of breast cancer is increasing fastly, women average age of onset 10 years earlier than in Europe and America! In the recently held Asian Breast Cancer Society of the sixth biennial meeting, the experts pointed out that the study found that breast cancer patients, 25% to 30% of the HER2 receptor is over for this type of breast cancer, scientists have found ways to delay its progression.

Asian women, average age of onset of breast cancer 10 years earlier

It is reported that new cases of breast cancer worldwide each year as many as 120 million people in the United States alone each year, 230,000. Breast cancer incidence and level of economic development, race relations and others have, including low incidence of blacks than whites, the more economically developed regions the higher incidence, such as New York, the incidence of districts in more than 100 per 100,000, while in China now has reached 100,000 30.

It should be noted that, although the vast majority of breast cancer patients are women, but men also suffer from breast cancer. Statistics show that in breast cancer patients, 1% were male.

ZHOU Yong-chang, president of the Asian Breast Cancer Society, said that in recent years, the increasing incidence of breast cancer in Asia. Since 1994, breast cancer rates of women living in the first, following lung cancer and colon cancer, the women become the third most deadly cancer. Among them, many European and American women with breast cancer incidence after the age of 50, while the average age of onset of the Asian women at least 10 years. ZHOU Yong-chang said, increasingly higher incidence of breast cancer, related to many factors. Such as urbanization, people face growing pressure, will affect the endocrine conditions, leading to hormonal imbalances, which occur genetic mutations. In addition, bad living habits and environmental pollution also affect the incidence of breast cancer. Studies have shown that women aged 16 to 20 years old smoke, the risk of breast cancer will be more troubles.

HER2 breast cancer, more likely to relapse than other types

ZHOU Yong pointed out that Hong Kong every year about 2000 new cases of breast cancer diagnosis, approximately 25% to 30% is too much HER2 type. HER system consists of four epidermal growth factor receptor, HER1 and HER2 in which growth and survival of cancer cells plays an important role. HER and cancer combined, the two sides "marriage" will give birth to a baby villain - "enzyme", once the enzyme is activated, it passes the signal, so that cancer cells continue to divide multiply, spread havoc in the patient's body. Study, HER2 excessive tumor growth rate faster than other types of breast cancer, women who suffer from breast cancer have a higher recurrence rate, but also more difficult to pre-diagnose the condition, in addition, one-third HER2 over-type women with metastatic breast cancer will develop into brain diffusion. Once breast cancer development to this stage, the progression of the disease is easy to get out of control, starting from the diagnosis, most patients an average of only 20% chance to survive one year.

Scientists find too much HER2-type breast tumors, "nemesis"

For the type of breast cancer treatment, scientists have done a lot of work. ZHOU Yong-chang said, a recent new developments is too much HER2-type breast tumors found a "nemesis." The study found that a new oral drug, its unique small molecules can enter cells, inhibit the enzyme is activated, thus inhibiting growth of cancer cells. The drug in breast cancer patients before and after taking all the more significant results. Taken before surgery may reduce the scope of the cancer lesion, breast-conserving increase the probability of surgery with chemotherapy, radiotherapy and other drugs, can remove the cancer, slow the spread of cancer process. 6000 patients participated in the current global clinical research, found that had received intensive therapy for the proliferation of patients, stable disease period may be extended to 90%, worsening the risk can be reduced by 43% for inflammatory breast cancer, its clinical effective rate was 82%. Reporters learned that, although the drug's tolerability and side effects are relatively small, but a course in the United States approximately 2,000 to $ 3,000, when in the country to achieve localization, reduce production costs, it is unknown.

Tips

Self-week period may prevent breast cancer

ZHOU Yong pointed out that for breast cancer, the most important thing is early prevention and early treatment. Fibrous tumor in the breast and breast hyperplasia, there is 1 / 200 will translate into breast cancer, in particular, need to be careful. Best women in the first week after the menstrual period to do self-test, some hyperplasia occurs during menstruation, most people shrink after the menstrual period, Zhege need to worry about, but there are a few people do not shrink, this happens, it should Danxin and take notice. Women over the age of 40 should be done at least twice per year B-1 X-ray, if you find problems, we must find a specialist referral.
