As the body ages, it undergoes various physiological changes that can increase the likelihood of cyst formation in different parts of the body. While many cysts are harmless, understanding which ones are linked to aging and when to seek medical advice is crucial for maintaining your health. Certain types of cysts, such as simple renal and hepatic cysts, become notably more common as people get older due to natural tissue degeneration and fibrosis. In contrast, some functional cysts, like ovarian ones in pre-menopausal women, are directly tied to hormonal cycles.
Why do cysts become more common with age?
The reason certain types of cysts become more prevalent with age varies depending on the specific cyst. Broadly, the causes can be linked to the following age-related factors:
- Cellular changes: As the body ages, cell renewal and shedding processes can become less efficient. In the skin, this can lead to the buildup of keratin and other cellular debris, resulting in epidermal cysts.
- Organ-specific degeneration: In organs like the kidneys, aging leads to gradual tissue degeneration and nephrosclerosis, which can cause tubular diverticula to form. These pouches can eventually fill with fluid, becoming simple renal cysts. Similarly, age-related fibrosis can contribute to hepatic cyst development.
- Hormonal shifts: The hormonal fluctuations that govern menstrual cycles in younger women can lead to functional ovarian cysts. After menopause, however, the absence of these cycles means that cysts that do form are not functional and have a slightly higher risk of being malignant, especially if they are complex or large.
- Repeated trauma or irritation: In some cases, years of minor injuries or irritation can lead to cyst formation. For instance, an old injury can cause a skin cyst to form by pushing surface skin cells deeper under the skin, creating a keratin-filled pocket.
Common age-related cysts
Benign skin cysts and growths
Many growths that appear on the skin with age are benign and non-cancerous.
- Seborrheic Keratoses: While not a true cyst, these waxy, "stuck-on" looking growths often contain small cyst-like structures and become significantly more common after age 50.
- Epidermoid Cysts: These cysts develop from blocked hair follicles and contain keratin. They are most common between the ages of 20 and 60, but can appear at any age.
- Lipomas: These slow-growing, benign tumors of fatty tissue can feel like a soft, rubbery lump under the skin and are often found in older adults.
Internal cysts
Cysts can also develop within organs, with frequency often rising with age.
- Simple Kidney Cysts: Found in the kidneys, these fluid-filled sacs are particularly common in those over 40 and increase in number and size with age. They are typically harmless.
- Hepatic Cysts: The prevalence of liver cysts increases significantly with age, and they are generally benign.
Gender-specific cysts
Some cysts are related to the reproductive organs and are influenced by age and hormonal changes.
- Ovarian Cysts: Functional cysts are common in pre-menopausal women and are linked to the menstrual cycle. While less common after menopause, any ovarian cyst that does form in older women, especially if it's complex, warrants careful monitoring due to a heightened risk of malignancy.
Comparing benign and potentially problematic cysts by age
| Feature | Benign Cysts | Potentially Problematic Cysts |
|---|---|---|
| Appearance | Uniform, symmetrical shape. Can be waxy, smooth, or firm depending on type. | Irregular shape or border. May have solid components or thick walls. |
| Symptom Profile | Often asymptomatic, unless they become irritated, infected, or grow large enough to cause pressure or pain. | May cause persistent or severe pain, abnormal bleeding, bloating, rapid growth, or changes in urinary/bowel function. |
| Location | Commonly found in predictable locations like the scalp, back, face, or kidneys. | Can appear in various locations, but those in certain areas, like a postmenopausal ovarian cyst, raise more concern. |
| Age Factor | Frequency and number may increase with age, such as with simple renal and hepatic cysts. | A new or changing cyst in an older adult, particularly an ovarian one post-menopause, is more likely to be investigated for potential malignancy. |
| Growth Pattern | Grow slowly or remain stable. Simple ovarian cysts in postmenopausal women often resolve on their own. | Rapid growth, a sudden eruption of multiple growths, or a lesion that changes color or shape. |
When to be concerned and see a doctor
Most cysts are benign, but a medical evaluation is recommended for any new or changing growth to rule out more serious conditions, especially with age. Here are some warning signs that warrant a doctor's visit:
- Rapid growth: A cyst that enlarges quickly should be evaluated promptly.
- Pain or infection: Cysts that become red, tender, or painful, particularly with fever, may be infected.
- Changes in appearance: If a skin cyst changes shape, color, or bleeds, it's best to have a dermatologist check it to differentiate it from skin cancer.
- Systemic symptoms: For internal cysts, symptoms like persistent bloating, pelvic or abdominal pain, unexplained weight loss, or changes in urination or bowel movements warrant immediate medical attention.
- Postmenopausal ovarian cysts: Any ovarian cyst discovered after menopause should be thoroughly evaluated by a gynecologic oncologist, as the risk of malignancy is higher than in younger women.
Conclusion
In short, it is normal to get cysts as you age, as many benign skin and internal cysts become more prevalent later in life due to natural physiological processes. While most are harmless, it is important to be aware of the different types and their risk factors, particularly with internal cysts like ovarian ones in older women. Regular checkups and prompt medical evaluation for any concerning changes are the best way to ensure peace of mind and protect your health. If a cyst is painful, growing rapidly, or causing systemic symptoms, seek medical advice promptly to ensure an accurate diagnosis and appropriate management. Consulting with a healthcare provider can help you understand whether your particular cyst is a normal sign of aging or requires further investigation.
