Breast cancer is the most common type of cancer among women and also the most life-threatening. Early diagnosis at stages amenable to full surgical resection and curative therapy has been made possible by increased public awareness and enhanced screening. As a result, breast cancer survival rates have considerably increased, especially for younger women.
A change or mutation of DNA and/or RNA causes cancer cells to develop from normal precursors. Cancer cells have comparable (but not identical) DNA and RNA to the cells of the organism from whence they arose. They are not frequently chosen by the immune system especially when it is weak. Hence, when the immune system is not functioning effectively, cancer can develop.
Under some circumstances, such as those involving an unfavorable environment (caused by radiation, chemicals, etc.), a bad diet (which creates an unhealthy cell environment), persons genetically predisposed to mutations, and the elderly, the rate of DNA and RNA mutations may be excessive. Cell division is uninterrupted and uncontrolled in malignant cells, which leads to cell proliferation and tumor formation.
Breast cancer is a term used to describe malignancies that develop from breast tissue, most frequently from lobules that feed the milk ducts or the inner lining of the ducts. Although breast cancer affects females more frequently than males, the latter have worse results due to delayed detection.
The glandular tissues and the stromal (supporting) tissues are the two basic tissue types that make up the breast. While stromal tissues are made up of fatty and fibrous connective tissues, glandular tissues house the lobules and ducts that produce milk. The immune system's lymphatic tissue, which eliminates waste and cellular fluids, is also a component of the breast tissue.
There are several kinds of tumors that can appear in the breast region. The majority of breast tumors are caused by benign (non-cancerous) alterations.
This was a glance at breast cancer. However, there is a lot to explore especially with active ongoing research.
