Understanding Cysts: Types, Causes, and Symptoms

Cysts are classified by origin, location, and content. Common types:

1. Epidermal (Sebaceous/Pilar) Cysts: Non-cancerous, keratin-filled, in top skin layer.
2. Ganglion Cysts: Fluid-filled, near joints/tendons (wrist, hand, foot, ankle).
3. Ovarian Cysts: Fluid sacs on ovaries; functional (resolve spontaneously) or pathological (dermoid, cystadenoma).
4. Breast Cysts: Fluid-filled sacs in breast tissue; usually benign, common in women 30-50.
5. Renal (Kidney) Cysts: Simple (benign) or complex (may need monitoring/treatment).
6. Liver Cysts: Usually benign/asymptomatic; large/multiple may need intervention.
7. Pancreatic Cysts: Benign, pre-malignant, or malignant; require professional evaluation.
8. Bone Cysts: Fluid-filled bone spaces; some benign (unicameral, aneurysmal), others cancerous (osteosarcoma).
9. Dermoid Cysts: Congenital; contain skin, hair, nails, teeth; ovaries (women) or scrotum (men).
10. Pilonidal Cysts: Near tailbone; contain hair, skin debris; can infect/inflame.

Consult a healthcare professional for any unusual bumps/swelling for accurate diagnosis and treatment.
