Cysts grow primarily due to fluid accumulating in a sac-like structure beneath the skin's surface. This accumulation can stem from various causes, making it crucial to understand the underlying mechanisms.
Common Causes of Cyst Growth
One of the most prevalent reasons for skin cyst formation is the blockage of sebaceous glands. These glands are responsible for lubricating the skin; when blocked, the secreted oil accumulates, creating a cyst. Think of it like a clogged pipe leading to a buildup of water.

Blocked Sebaceous Glands: As mentioned, a clogged sebaceous gland prevents the natural flow of oil, leading to fluid accumulation and cyst formation. This is a very common cause of many types of skin cysts.
-
Injury or Irritation to a Hair Follicle: Trauma or irritation to a hair follicle can also trigger cyst development. The body's inflammatory response to the injury may lead to fluid buildup, forming a cyst.
-
Other less common causes: While less frequent, other factors can contribute to cyst formation including infections, genetic predisposition, and certain medical conditions. Further investigation is often needed to pinpoint the specific cause in these cases.
Understanding Cyst Formation
The process of cyst growth involves the formation of a membrane surrounding the accumulated fluid. This membrane can be fibrous or epithelial, depending on the type of cyst. The fluid within the cyst can vary in consistency, ranging from watery to thick and cheesy, depending on the underlying cause. The cyst continues to grow as more fluid accumulates within this enclosed sac.
