- Medical History: The healthcare provider will ask about your symptoms, their duration, and any related health conditions or family history.
- Physical Examination: The provider will palpate (feel) the area where the cyst is suspected to check for lumps, tenderness, and other characteristics.
2. Imaging Tests
- Ultrasound: Often the first imaging test used for evaluating cysts. It helps to determine if a cyst is solid or fluid-filled and to assess its size and location. Commonly used for ovarian, breast, and kidney cysts.
- CT Scan (Computed Tomography): Provides detailed cross-sectional images of the body and is used to evaluate the cyst’s structure and surrounding tissues. Useful for complex cysts or those in deeper areas.
- MRI (Magnetic Resonance Imaging): Offers detailed images of soft tissues and is used when more information about the cyst’s characteristics is needed. Helpful for evaluating cysts in the brain, spine, or complex ovarian cysts.
3. Laboratory Tests
- Blood Tests: May be used to check for markers of infection, inflammation, or other systemic conditions. For example, elevated white blood cell count might suggest an infection if the cyst is inflamed.
- Urinalysis: Can help detect issues related to kidney cysts, such as blood or infection in the urine.
4. Biopsy
- Needle Aspiration: Involves using a needle to withdraw fluid from the cyst for analysis. This can help determine whether the cyst is benign or malignant. It’s often used for breast or ovarian cysts.
- Core Needle Biopsy: A larger needle is used to remove a small sample of tissue from the cyst for examination under a microscope. This is typically done if there’s concern about cancer.
5. Additional Tests
- Endoscopy: For cysts in the gastrointestinal tract or other internal organs, an endoscope may be used to visually inspect the area and possibly take a biopsy.
- Pap Smear: For cysts in the cervix or if there’s a suspicion of a related issue, a Pap smear might be performed to check for abnormalities.
Diagnosis Based on Specific Cyst Types:
Epidermoid and Dermoid Cysts
- Physical Examination: Often sufficient to diagnose these types. Imaging may be used if there is any uncertainty about their nature.
Ovarian Cysts
- Ultrasound: Primary tool for evaluation. It helps determine the cyst’s type and whether it’s functional or pathological.
- CT or MRI: Used if there are complications or unusual findings.
Kidney Cysts
- Ultrasound: To differentiate between simple and complex cysts.
- CT Scan: To further evaluate complex cysts.
Breast Cysts
- Ultrasound: Helps differentiate between fluid-filled cysts and solid masses.
- Mammography: May be used in conjunction with ultrasound for a more comprehensive assessment.
- Biopsy: If a solid mass or suspicious features are detected, a biopsy may be performed.
Pilonidal and Ganglion Cysts
- Physical Examination: Usually sufficient for diagnosis. Imaging might be used if the cyst is deep or if there are concerns about other conditions.
Bartholin’s Cyst
- Physical Examination: Examination of the area can confirm the presence of the cyst.
- Aspiration: May be performed to relieve symptoms and confirm the diagnosis.
Hydatid Cyst
- Imaging (CT or MRI): To visualize the cyst and assess its impact on surrounding tissues.
- Serological Tests: To detect antibodies to the Echinococcus parasite.
Treatment IN INDIA:
1. Observation

Cysts can form due to a variety of causes:
1. Epidermoid Cysts
- Cause: Develop from the proliferation of epidermal cells. These cells can become trapped under the skin, leading to a cyst formation.
- Triggers: Often arise due to skin trauma, such as acne, or due to genetic factors.
2. Dermoid Cysts
- Cause: Result from developmental abnormalities where skin cells and other tissues become trapped during fetal development.
- Triggers: Generally congenital, meaning they are present from birth.
3. Ovarian Cysts
- Types and Causes:
- Functional Cysts: Form as part of the normal menstrual cycle. Follicular cysts occur when a follicle fails to rupture and release an egg. Corpus luteum cysts occur when the follicle’s lining doesn’t dissolve after ovulation.
- Pathological Cysts: Include endometriomas (caused by endometriosis), dermoid cysts (containing different types of tissues), and cystadenomas (developing from ovarian tissue).
4. Polycystic Ovarian Syndrome (PCOS)
- Cause: A hormonal disorder characterized by the presence of multiple small cysts on the ovaries.
- Triggers: Insulin resistance, genetic factors, and hormonal imbalances.
5. Kidney Cysts
- Types and Causes:
- Simple Kidney Cysts: Often develop as part of the aging process, where fluid-filled sacs form within the kidney.
- Complex Kidney Cysts: May arise from conditions such as polycystic kidney disease (genetic) or due to other kidney disorders.
6. Breast Cysts
- Cause: Often related to hormonal changes, particularly fluctuations in estrogen levels.
- Triggers: Hormonal changes associated with the menstrual cycle, pregnancy, or menopause.
7. Pilonidal Cysts
- Cause: Develop from a combination of factors, including ingrown hairs, friction, and skin infections.
- Triggers: Poor hygiene, prolonged sitting, and trauma to the area. More common in people with excessive body hair.
8. Ganglion Cysts
- Cause: Form from the leakage of synovial fluid (fluid from around the joints or tendons) into the surrounding tissue.
- Triggers: Often linked to joint or tendon stress or injury.
9. Baker’s Cyst
- Cause: Develops from a swelling of the popliteal bursa behind the knee, usually due to knee joint issues like arthritis or a meniscus tear.
- Triggers: Knee joint inflammation or injury.
10. Bartholin’s Cyst
- Cause: Arises when the Bartholin’s gland becomes blocked, preventing the gland’s fluid from draining properly.
- Triggers: Can be caused by infection, inflammation, or trauma.
11. Chalazion
- Cause: Results from the blockage of a meibomian gland in the eyelid, leading to the accumulation of oil and inflammation.
- Triggers: Often follows an eyelid infection or inflammation, such as blepharitis.
12. Hydatid Cyst
- Cause: Caused by infection with the Echinococcus parasite (tapeworm) that forms cysts in the liver, lungs, or other organs.
- Triggers: Infection occurs from ingesting parasite eggs, often through contact with infected animals or contaminated food.
Summary
- Genetic Factors: Many cysts have genetic underpinnings, such as polycystic kidney disease or dermoid cysts.
- Hormonal Imbalances: Particularly relevant for ovarian, breast, and PCOS-related cysts.
- Trauma or Infection: Can trigger cyst formation or exacerbate existing cysts, such as in pilonidal cysts or epidermoid cysts.
- Aging: Simple kidney cysts and some skin cysts are associated with the natural aging process.
