When cells begin to proliferate uncontrollably, they become cancerous. It’s critical to realize that most breast lumps aren’t cancerous (malignant). There is no evidence to suggest that benign, noncancerous breast tumours can spread outside the breast. Examine any change or swelling in your breast by a medical professional to determine whether it is benign or malignant and if it impacts your future risk of breast cancer. If you suspect lumps on your breasts, get help from a breast cancer specialist.
Various parts of the breast can be the source of breast cancer. The breast supports the chest muscles and upper ribs. The glands, ducts, and fatty tissue that make up the breasts can be found on both the left and right sides of the body. The size of each breast is determined by the fat level of the mammary gland. Breast milk is produced and delivered by women to feed infants and newborns.
However, we do know that genetic mutations cause breast cancer. However, only one in ten (10%) breast cancer cases are thought to be caused by abnormal genes passed down from parents (inherited). Women with a family history of breast cancer may have inherited an abnormal gene that does not appear on a genetic test. Unknown genetic mutations are the primary cause of most breast cancers (about 90%).
Most breast cancer gene mutations are acquired. In other words, the mutation occurs in the breast cells of a person throughout their life rather than being passed down through genetics. Breast cancer cells only have acquired DNA mutations due to the disease’s progression over time. If you notice any unusual symptoms, get help from a breast cancer specialist as soon as possible.
Cancer-causing agents, such as radiation, may also play a role in developing oncogene and tumour suppressor gene mutations. However, some gene changes may result from chance events occurring within a cell occasionally. Since most breast cancer-causing mutations are still unknown, it is difficult to speculate about their origins.
Low-penetrance genetic changes or gene variants are more frequently implicated in cancer development than previously thought. Because these mutations are so common and people seem to have more than one simultaneously, the overall impact on the population can be pretty significant. When it comes to breast cancer risk, the genes involved can impact things like hormonal changes and metabolism, among other things.
