Cherry Disease: Everything You Need to Know About Red Skin Spots
Have you ever noticed small, bright red spots appearing on your torso or arms as you get older? While they might look alarming, these spots—often colloquially referred to as cherry disease—are almost always harmless. In the medical world, these common skin growths are known as cherry angiomas. They are a natural part of the ageing process for many, but understanding why they appear and how to manage them can provide much-needed peace of mind.
In this guide, we will explore what causes these red moles, when you should speak to a professional in dermatology, and the modern treatments available to clear your skin.
What Exactly Is Cherry Disease?
When people search for “cherry disease” in a medical context, they are typically describing cherry angiomas. These are small, circular, or oval-shaped bumps that range in colour from bright red to deep purple. While the word “disease” sounds serious, these are actually benign tumours consisting of an overgrowth of small blood vessels.
According to the NHS, these spots are non-cancerous and do not spread like an infection. They are the result of capillary proliferation, where the tiny vessels near the surface of the skin clump together. Though they can appear anywhere on the body, they are most frequently found on the trunk, shoulders, and back.
What Causes These Red Spots to Appear?
The exact cause of cherry angiomas remains a subject of ongoing research, but several factors are known to play a significant role. If you are noticing more of these spots as you reach your 30s or 40s, you are certainly not alone. Experts at Mayo Clinic suggest that more than 50% of adults over the age of 30 have at least one.
Common contributing factors include:
- Ageing skin: The prevalence of these spots increases significantly as we age.
- Genetic predisposition: If your parents had many cherry angiomas, you are more likely to develop them too.
- Hormonal changes: Significant shifts in hormones, such as during pregnancy, have been linked to a sudden increase in these spots.
- Environmental factors: Some studies in Nature have looked into the link between chemical exposure (such as bromides) and angioma development.
- Sun exposure: While not a direct cause, chronic sun exposure can damage the skin’s structure, making vascular issues more visible.
The Role of Genetics and Age
Research published on PubMed indicates that genetic predisposition is one of the strongest predictors for developing multiple angiomas. As the skin loses elasticity and the vascular walls weaken with ageing skin, these clusters of blood vessels become more prominent.
Identifying Cherry Angiomas vs. Other Skin Conditions
It is crucial to distinguish cherry disease from more serious issues like melanoma or other forms of skin pigmentation. Cherry angiomas are typically firm to the touch and do not bleed unless they are scratched or caught on clothing. Unlike many other marks, they do not usually change shape or colour rapidly.
To help you understand the differences, here is a comparison of common skin spots:
| Feature | Cherry Angioma | Malignant Melanoma | Normal Mole |
|---|---|---|---|
| Colour | Bright red or purple | Multi-coloured, black, or brown | Uniform brown or tan |
| Shape | Symmetrical, round/oval | Asymmetrical, irregular borders | Symmetrical, round |
| Texture | Smooth or slightly raised | Scaly, crusty, or bleeding | Flat or slightly raised |
| Health Risk | Benign (Harmless) | High (Cancerous) | Low (Usually benign) |
Treatment Options for Cherry Angiomas
Because these spots are benign, treatment is usually sought for cosmetic reasons or if the spot is located in an area where it frequently becomes irritated. If you decide to remove your “cherry disease” spots, several professional options are available through a qualified dermatologist.
- Laser therapy: A Pulsed Dye Laser (PDL) is often used to target the blood vessels specifically. The heat from the laser destroys the vessel without damaging the surrounding skin.
- Cryosurgery: This involves freezing the growth with liquid nitrogen. According to DermNet NZ, this is a quick and effective method, though it may leave a small white scar.
- Electrocautery: This method uses a small probe with an electric current to burn the angioma away. It is highly effective for smaller spots.
- Shave Excision: For very large or raised spots, a doctor may surgically “shave” the growth off the surface of the skin.
It is important to avoid “at-home” removal kits. Attempting to cut or burn these spots yourself can lead to significant bleeding, scarring, and infection. Always consult a professional at an organisation like the British Skin Foundation before attempting any treatment.
When Should You See a Doctor?
While most cases of cherry disease are a purely cosmetic concern, you should always monitor your skin for changes. The Cleveland Clinic recommends seeking medical advice if you notice the following:
- The spot begins to bleed frequently or spontaneously.
- The growth changes rapidly in size, shape, or colour.
- The border of the spot becomes blurred or irregular.
- You have a sudden, eruptive appearance of dozens of new spots (which can sometimes indicate an internal health issue).
A specialist can perform a skin biopsy if there is any doubt about the nature of the lesion. You can find more detailed medical studies on vascular skin issues via ScienceDirect.
Managing Your Skin Health Long-Term
While you cannot entirely prevent the capillary proliferation that leads to cherry angiomas, maintaining overall skin health is vital. Protecting your skin from excessive sun exposure and staying hydrated can help maintain the integrity of your blood vessels. For more general advice on maintaining healthy skin as you age, resources like Harvard Health and Patient.info offer excellent lifestyle tips.
Remember, these spots are a very common part of the human experience. Whether you choose to embrace them or have them removed via laser therapy, they are a minor detail in the grand scheme of your health. If you are ever worried, a quick check-up with a GP or dermatologist, as recommended by WebMD, can provide the reassurance you need.
Frequently Asked Questions (FAQs)
Can cherry disease turn into cancer?
No, cherry angiomas are strictly benign tumours. They do not have the potential to become malignant. However, because they can look similar to other skin conditions, any new or changing spot should be evaluated by a healthcare professional to rule out other issues.
Are these spots caused by a poor diet?
There is currently no strong scientific evidence linking diet directly to the development of cherry angiomas. They are primarily driven by genetic predisposition, hormonal changes, and the natural process of ageing skin.
Do cherry angiomas go away on their own?
Generally, no. Once a cherry angioma forms, it usually stays on the skin unless it is removed through medical procedures like cryosurgery or electrocautery. They may occasionally disappear if the blood vessel within them becomes clotted, but this is rare.
Is it safe to use essential oils to remove them?
There is no clinical evidence that essential oils or topical creams can remove these skin growths. Because they are clusters of blood vessels deep within the dermis, surface treatments are rarely effective and may cause skin irritation.
