I don't know how many cancer patients and their families will have a series of questions in their minds after being told that the tumor is diagnosed. Today, let's learn about breast cancer together, hoping to help more breast cancer patients and their families.
Globocan20 12 data shows that the number of new breast cancer cases in the world is 167 1 10,000, and the world standardized incidence rate is 43.1110,000, with an incidence rate of 25%, which still ranks first in the incidence rate of female malignant tumors. There are 522,000 breast cancer deaths worldwide, with the world standardized mortality rate of12.9/100000, and the death composition of 14.7%, ranking first among women.
According to "Cancer Incidence and Death in China from 2003 to 2007" and "Analysis of Cancer Incidence and Death in China from 20 12" published by Chen Wanqing et al., the changes of standardized incidence and mortality of breast cancer in China from 2012 in 2003 are as follows: from 2003 to 2008, the incidence of female breast cancer in China changed from 2/kloc-0. However, in 20 10-20 12, the incidence rate rose sharply to 30.43/100000, an increase of 43.73% compared with 2003. From 2003 to 20 12, the average annual change percentage of female breast cancer incidence in China was 3.55%.
From 2003 to 2009, the standardized mortality of female breast cancer in China fluctuated relatively little, but it increased greatly from 20 10 to 20 12. In recent ten years, the average annual change rate of breast cancer mortality is 3.87%.
The high incidence age of breast cancer in China is 45-55 years old, and the median age of onset is about 50 years old. 57.4% of breast cancer patients get sick before 50 years old.
If there is a family history of breast cancer, and there are mutations in BRCA 1 and BRCA2 in the genes that induce breast cancer, some patients will also develop breast cancer when they are young. Therefore, it is suggested that people with gene mutation should be closely monitored in order to find and treat diseases early and improve the cure rate.
Breast cancer is a kind of tumor with good prognosis among all kinds of cancers. If the tumor is diagnosed as an early localized lesion without axillary lymph node metastasis, the 5-year survival rate after breast surgery is extremely high, which can also be said to be cured. According to Beijing cancer data released by Beijing Cancer Research Office, the 5-year survival rate of breast cancer patients in Beijing is about 80.77%.
But the high postoperative cure rate of early breast cancer does not mean that there is no chance of recurrence. If it belongs to triple negative breast cancer or advanced breast cancer, the recurrence period is high within 5 years after operation, and the recurrence risk is the highest in 1 ~ 3 years after operation. Although the size of the tumor itself, whether there is lymph node metastasis or not, and the type of receptor will vary from person to person, more evidence shows that the treatment of breast cancer patients within 1 ~ 3 years after operation is very important. As long as the risk of recurrence is successfully controlled, breast cancer patients can have a long survival period. If breast cancer recurs or metastasizes, it will greatly increase the difficulty of treatment and directly threaten the life of patients. After distant metastasis of breast cancer, the survival rate of patients will be significantly reduced, such as the 5-year survival rate of bone metastasis is 16%, the 5-year survival rate of lung metastasis is 12%, and the 5-year survival rate of liver metastasis is almost zero.
Finally, in order to reduce the risk of breast cancer, several suggestions are given to the majority of female compatriots: exercise more; Drink less and quit smoking; Avoid obesity; Don't stay up late; Eat less fried and high-fat and high-calorie foods; Insist on breastfeeding after delivery; Health care products and cosmetics without hormones; Menopausal women should use estrogen replacement therapy with caution; Regular physical examination, adhere to self-inspection; Enhance your own resistance and stay away from tumors.
