There are many types of breast cancer. The most common types are ductal carcinoma in situ, invasive ductal carcinoma, and invasive lobular carcinoma. The type of breast cancer is determined by the specific cells in the breast that are affected.
There are different types of breast lumps. The following descriptions and illustraitons provides some details. If you have any questions, follow-up with your doctor.
Breast tissue is found in the breast, upper chest and the armpit. Each breast contains glands called lobes, where milk is produced. These lobes are connected to the nipple by tubes called ducts.
Multiple studies have shown that women with mammographically dense breasts are at a higher risk of developing breast cancer and that the upper outer quadrant of the breast is the most frequent site where breast cancer is located. There is no association, according to findings of a study published in BMC Cancer. However, the study did reconfirm that breast cancer was most likely to occur in the upper outer quadrant of the breast in a patient cohort of women. Research to investigate the relationship between quadrant density and tumors occurring in a specific quadrant location has been limited by lack of a reliable method to measure quantitative density on mammography as well as by lack of a standardized method to divide a breast into four well-defined quadrants.
To investigate the relationship between mammographic density measured in four quadrants of a breast with the location of the occurred cancer. One hundred and ten women diagnosed with unilateral breast cancer that could be determined in one specific breast quadrant were retrospectively studied. For tumor location, 67 women
Lifelong nuns, like all women who never have children, are at an increased risk of dying from breast, ovarian and uterine cancers, compared with mothers. A woman's risk of getting these cancers increases with the number of menstrual cycles she experiences. It is not only humans who suffer from breast cancer, some animals do too.
Breast cancer is cancer that develops from breast tissue. Risk factors for developing breast cancer include being female, obesitylack of physical exercise, drinking alcoholhormone replacement therapy during menopauseionizing radiationearly age at first menstruationhaving children late or not at all, older age, prior history of breast cancer, and family history. The balance of benefits versus harms of breast cancer screening is controversial. A Cochrane review stated that it is unclear if mammographic screening does more good or harm.
Women and men both have breasts, but women have more breast tissue than men. The breasts contain mammary glands. Only the mammary glands in women can make milk to feed a baby.
Each breast contains 15 to 20 lobes of glandular tissue, arranged like the petals of a daisy. The lobes are further divided into smaller lobules that produce milk for breast-feeding. Small tubes ducts conduct the milk to a reservoir that lies just beneath your nipple. After skin cancer, breast cancer is the most common cancer diagnosed in women in the United States.
