BRCA1 and BRCA2 mutations are genetic alterations that significantly increase the risk of breast and ovarian cancer by impairing DNA repair mechanisms. These mutations can be inherited and are crucial for guiding decisions on preventive measures and personalized cancer treatment strategies.

Genetic alterations refer to changes in the DNA sequence that can result in variations in gene expression or function, potentially leading to diseases or beneficial traits. These alterations can occur naturally or be induced artificially, and they play a critical role in evolutionary biology, medicine, and biotechnology.

Genetic Alterations

Breast cancer is a malignant tumor that develops from breast cells and is one of the most common cancers affecting women worldwide, though it can also occur in men. Early detection through screening and advances in treatment have significantly improved survival rates, making awareness and timely medical intervention crucial.

Breast Cancer

Ovarian cancer is a malignant tumor that originates in the ovaries, often diagnosed at a late stage due to subtle symptoms and lack of effective early screening tests. Treatment typically involves a combination of surgery and chemotherapy, with prognosis dependent on the stage at diagnosis and the cancer's response to treatment.

Ovarian Cancer

DNA repair mechanisms are essential cellular processes that correct damage to the DNA structure, ensuring genomic stability and preventing mutations that could lead to diseases like cancer. These mechanisms involve a variety of pathways that recognize and repair different types of DNA damage, maintaining the integrity of genetic information across cell generations.

Inherited Mutations

Preventive measures are proactive strategies designed to avert the onset of diseases or problems, thereby reducing the need for treatment or intervention. They encompass a wide range of activities, including lifestyle modifications, vaccinations, and regular screenings, aimed at maintaining health and preventing future complications.
