Hereditary breast cancer: targeted therapy and artificial intelligence to improve diagnosis

Breast cancer can spread when cancer cells reach the blood or lymphatic system and spread to other parts of the body.

Researchers said artificial intelligence is improving screening techniques and could help personalize early diagnosis of carriers, emphasizing which early detection techniques and which genes should be considered for diagnosis .

This pathology occurs in ten percent of cases, and experts say that this hereditary mutation does not mean that a person will develop a tumor, but rather that they are more likely to develop it throughout their lives.

One of the most important aspects during the event is that genetic mutations in BRCA1 and BRCA2 have been found in 30 percent of women who meet the criteria for this type of cancer, despite the fact that it involves other genes, Such as, among others, PALB2, PTEN, CDH1, TP53, CHEK2 or ATM.

The American Cancer Association says it is important to know that most breast lumps are benign and not cancerous (malignant). Noncancerous (benign) breast tumors are abnormal growths, but they have not spread outside the breast.

These tumors are not life-threatening, although some types of benign lumps can increase a woman’s risk of breast cancer. Any lump or change in the breast should be examined by a health care professional to see if it is benign or malignant (cancerous), and whether it could affect your future cancer risk. For more information, see Non-cancerous breast conditions.

Where does breast cancer start?

Breast cancer can start in different parts of the breast.

*Most breast cancers start in the tubes that carry milk to the nipples (ductal cancer)

* Some cancers begin in the milk-producing glands (lobular cancer)

* There are other types of breast cancer that are less common such as Phyllodes tumor and angiosarcoma

* A small number of cancers begin in other tissues of the breast. These cancers are called sarcomas and lymphomas, and are not actually considered breast cancer.

Although many types of breast cancer can cause lumps in the breast, not all do. Check out the signs and symptoms of breast cancer to find out what to look for and when to tell your doctor. Many breast cancers are also discovered on screening mammograms that can show cancer in its earlier stages, often before they are felt and before symptoms develop.
