Nearly half of all women aged 40 and older are found to have dense breast tissue, which falls into one of four categories: Category A: Breasts are almost all fatty tissue.

Dense breast tissue is normal and occurs in nearly half of all women over 40. Typically, breast density decreases as you age. Only 25% of women over 60 have dense breast tissue.

There are four categories of breast density, ranging from almost all fatty tissue to extremely dense tissue with very little fat. Having dense breasts is actually physiologic, present in about 50 percent of ...
This communication must explain what breast density consists of, whether the patient has dense tissues or not, and why breast density is a risk for breast cancer.

It’s similar to having a first-degree relative with breast cancer. Remember, dense breast tissue is very common and completely normal. Some 40-50 percent of premenopausal women ...

Table 1 breaks down breast density variety from the INbreast dataset. The distribution of breast densities variety across the four classes is shown in Table 1. As shown, it can be seen that the dataset is highly imbalanced with the lowest percentage (7%) of data belong to BI-RADS IV, and the highest percentage of data (35%) belong to BI-RADS II
