Anisomastia is a medical condition in which there is a severe asymmetry or unequalness in the size of the breasts, generally related to a difference in volume. [1] In other words, when one of the breasts is much larger than the other. [2] In contrast to anisomastia, a slight asymmetry of the breasts is common. [1]
Breast development is commonly asymmetric and one or both breasts may be small. This condition may be a congenital defect associated with underlying abnormalities of the pectoral muscle (as in Poland's syndrome [ 2 ] ), related to trauma (typically surgery or radiotherapy ) or it may be a more subjective aesthetic description.
The Canadian Task Force found that for women ages 50 to 69, screening 720 women once every 2 to 3 years for 11 years would prevent one death from breast cancer. For women ages 40 to 49, 2,100 women would need to be screened at the same frequency and period to prevent a single death from breast cancer. [4]
The indication is an excess breast weight that exceeds approximately 3% of the total body weight. [3] There are varying definitions of what is considered to be excessive breast tissue, that is the expected breast tissue plus extraordinary breast tissue, ranging from as little as 0.6 kilograms (1.3 lb) up to 2.5 kilograms (5.5 lb) with most physicians defining macromastia as excessive tissue of ...
Breast cancer is the most common cause of cancer death among women [69] and it is one of the leading causes of death among women. Factors that appear to be implicated in decreasing the risk of breast cancer are regular breast examinations by health care professionals, regular mammograms , self-examination of breasts , healthy diet, exercise to ...
A denser breast is more likely to develop breast cancer. [19] A dense breast is characterized by a meaningful amount of fibrous tissue , relatively to the adipose one. The main constituents of a fibrous tissue are water, collagen and hemoglobin and optical mammography is able to discriminate and quantify tissues' components. [ 2 ]
The basal-like carcinoma is a recently proposed subtype of breast cancer defined by its gene expression and protein expression profile. [1]Breast cancer can be divided into five molecular subtypes, including luminal subtype A, luminal subtype B, normal breast-like subtype, HER-2 overexpression subtype, and basal-like subtype. [2]
One of the most important factors in classifying a tumor as benign or malignant is its invasive potential. If a tumor lacks the ability to invade adjacent tissues or spread to distant sites by metastasizing then it is benign, whereas invasive or metastatic tumors are malignant. [3] For this reason, benign tumors are not classed as cancer. [27]
