A breast cyst is a cyst, a fluid-filled sac, within the breast. One breast can have one or more cysts. They are often described as round or oval lumps with distinct edges. In texture, a breast cyst usually feels like a soft grape or a water-filled balloon, but sometimes a breast cyst feels firm. [1]
A breast mass, also known as a breast lump, is a localized swelling that feels different from the surrounding tissue. [1] Breast pain, nipple discharge, or skin changes may be present. [1] Concerning findings include masses that are hard, do not move easily, are of an irregular shape, or are firmly attached to surrounding tissue. [2]
It is mainly used to differentiate between a cyst and a mass. [6] If the aspirated contents are not cyst-like, then a tissue sample must be taken to better evaluate the mass. [6] Fine-needle aspiration is one of the most commonly used initial diagnostic tools for suspicious lesions. [12]
The tumor is round or ovoid, elastic, and nodular, and has a smooth surface. The cut surface usually appears homogenous and firm, and is grey-white or tan in colour. The pericanalicular type (hard) has a whorly appearance with a complete capsule, while the intracanalicular type (soft) has an incomplete capsule. [9]
About 20% of breast cancers diagnosed in the U.S. each year are DCIS. Many of them do not go on to become cancers—but a small percentage of so-called high grade DCIS do, and doctors only have ...
On mammography, ILC shows spiculated mass with ill-defined margins that has similar or lower density than surrounding breast tissues. This happens only at 44–65% of the time. Architectural distortion on surrounding breast tissues is only seen in 10–34% of the cases. It can be reported as benign in 8–16% of the mammography cases. [10]
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] Women whose breast cancer was detected by screening mammography before the appearance of a lump or other symptoms commonly assume that the mammogram "saved their lives". [80]
Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses. [1] The breasts may be described as "lumpy" or "doughy". [3] Symptoms may worsen during certain parts of the menstrual cycle due to hormonal stimulation. [1] These are normal breast changes, not associated with cancer. [2]
