Involution cyst (ɪnvəˈluːʃən sɪst) is a benign cyst that can develop in the mammary gland tissue after pregnancy and lactation. The word "involution" refers to the process of shrinking or returning to a previous state, while "cyst" describes the sac-like structure that can form in various parts of the body. The phonetic transcription shows that the stress is on the second syllable of "involution" and the first syllable of "cyst," with the "sh" sound in "involution" represented by the IPA symbol ʃ.
An involution cyst is a type of cyst that occurs as a result of involution, which refers to the shrinkage or regression of an organ or tissue to its normal size following a period of growth or enlargement. In the case of an involution cyst, this refers specifically to a cyst that forms as a part of the involution process.
Typically, involution cysts are found in the breasts of women during their postpartum period. They can also occur in other organs or tissues undergoing involution, such as the uterus, ovaries, or prostate gland.
The exact cause of involution cysts is not fully understood, but they are believed to arise from the accumulation of fluid or secretions within the affected tissue. These cysts are usually benign and do not pose a significant health risk. However, in some cases, involution cysts can become enlarged, causing discomfort or pain.
Diagnosis of an involution cyst is usually made through imaging techniques such as ultrasound or mammography. Treatment is typically not necessary unless the cyst becomes symptomatic, in which case it may be drained or surgically removed.
In summary, an involution cyst is a benign cyst that develops as a result of involution, the process of an organ or tissue returning to its normal size after a period of growth. They are most commonly found in the breasts during the postpartum period but can occur in other organs as well. Although generally harmless, treatment may be required if the cyst causes significant discomfort or pain.

The term "involution cyst" does not have a specific etymology as it is a medical term that combines two separate words: "involution" and "cyst".
1. Involution: The word "involution" comes from the Latin word "involūtus", which is the past participle of the verb "involvĕre". It means to roll up, wrap up, or coil within. In medicine, involution refers to the process of shrinking, returning, or regressing to a previous state or condition. It commonly refers to the natural shrinkage or reduction in size of an organ after it has completed its function or activity. For example, after pregnancy, the uterus undergoes involution, returning to its pre-pregnancy size.
