What are the distribution characteristics of breast cancer and breast cancer?

Breast cancer is a malignant tumor that occurs in the epithelial tissue of the breast glands. It is one of the most common malignant tumors that seriously affect women's physical and mental health and even endanger life. Breast cancer is rare in men. Breast cancer is the mutation of genes in breast glandular epithelial cells under the action of various carcinogens, which leads to uncontrolled cell proliferation. Due to changes in the biological behavior of cancer cells, they present disordered and unlimited malignant hyperplasia. Its histological manifestation is that a large number of naive cancer cells proliferate infinitely and crowded into disorder, squeezing and eroding the surrounding normal tissues, and destroying the normal tissue structure of the breast.

Because the breast is not an important organ for human life activities, breast cancer in situ is not theoretically fatal and can be cured by surgical resection. But because the mammary gland cells are mutated, they lose the characteristics of normal cells, the tissue structure is disordered, the cells are loosely connected, and the cancer cells are easily shed and free. They spread throughout the body with blood or lymph fluid, forming an early distant metastasis to breast cancer. The clinical cure has increased greatly. The transfer of important organs in the whole body, such as lung metastasis, brain metastasis, and bone metastasis, will directly threaten human life. Therefore, breast cancer is a malignant disease that seriously threatens human life.

The principle of prevention and treatment of breast cancer is the same as that of all cancers, and it should strive for early detection and early treatment. In daily life, it is necessary to adhere to scientific breast care, breast self-examination and regular medical professional examinations.

Distribution characteristics of breast cancer?

Regional distribution: cities are higher than rural areas

In my country, breast cancer has become one of the most common malignant tumors in women. Although my country is a country with a low incidence of breast cancer, there is a clear urban-rural difference in breast cancer incidence. High-incidence areas are mainly concentrated in large coastal cities, with Shanghai as the highest. Especially in the past 20 years, the incidence of breast cancer in urban women has been increasing year by year. Taking Shanghai as an example, the incidence in 1999 was double that in 1974

More than that, so in some coastal cities in my country, breast cancer is already the most common malignant tumor in women.

Gender distribution: more women than men

Breast cancer is predominantly female, rare in men, and the incidence of females is about 100 times higher than that of males, so we generally refer to breast cancer as female breast cancer. The peak incidence of breast cancer in my country is between 40 and 60 years old. The statistics of breast cancer incidence in Shanghai in my country show that the incidence of breast cancer has an increasing trend in all age groups. The mortality rate of breast cancer in all ethnic minorities in my country is very low, but Mongolians and Kazakhs are slightly higher than other ethnic minorities, and the incidence of breast cancer among Tibetan women is the lowest.

Please learn to protect yourself

Early detection of breast cancer is far more important to patients than any current treatment plan. So for a period of time in the future, striving for early detection and early diagnosis is still the basic strategy to improve the efficacy of breast cancer.
