Cherry angiomas are extremely common, and having a lot of them is almost always a normal part of aging rather than a sign of something wrong. These small, bright red dots on the skin appear in about 7% of adolescents but show up in roughly 75% of adults over age 75. Between those two ends of the spectrum, the number tends to climb steadily with each decade, and some people simply accumulate more than others.
Age Is the Biggest Factor
The single strongest predictor of how many cherry angiomas you have is how old you are. Somewhere between 5% and 41% of people start developing them in their 20s, and from there, new ones keep appearing. By middle age, most people can count at least a few. By 75, three out of four people have them.
Each cherry angioma forms when the cells lining a tiny blood vessel begin to multiply slowly. A study examining 23 cherry angiomas under the microscope found active cell division in the vessel walls of every single one, though the rate of growth was low. This is why they tend to start as a pinpoint red dot and gradually expand to a few millimeters over months or years. They’re not cancerous growths; the replication rate is far too slow and orderly for that. But the process is ongoing, which is why they don’t shrink on their own once they appear.
Genetics and Family Patterns
If your parents had a lot of cherry angiomas, you’re more likely to as well. The tendency to develop them runs in families, though no single gene has been pinpointed as the cause. You may notice them appearing at a similar age as your parents did, or clustering in the same areas, particularly the torso, upper arms, and shoulders.
Hormonal Shifts Can Speed Things Up
Some people notice a burst of new cherry angiomas during pregnancy or other periods of significant hormonal change. Elevated estrogen levels promote blood vessel growth throughout the body, and cherry angiomas appear to be part of that response. This is also why some people on hormone therapy report more of them appearing. The angiomas that form during these periods are permanent, even after hormone levels return to normal.
Chemical and Environmental Exposures
Certain chemical exposures have been linked to clusters of new cherry angiomas. Bromide compounds are the best-documented trigger. The connection was first identified in workers exposed to bromides in industrial settings, and later case reports found the same pattern in patients using bromide-containing medications long term, including an asthma inhaler that contains ipratropium bromide. If you work with industrial chemicals or solvents and have noticed a sudden crop of new angiomas, the exposure could be a contributing factor.
When a Sudden Crop Deserves Attention
A gradual increase over years is normal. A sudden eruption of dozens of new cherry angiomas over weeks, sometimes called eruptive cherry angiomas, is less typical and worth mentioning to a doctor. While the angiomas themselves are still benign, a rapid onset can occasionally reflect hormonal shifts, chemical exposure, or other systemic changes that are worth investigating.
It’s also worth knowing that cherry angiomas and spider angiomas are different things, even though both are red and both involve blood vessels. Spider angiomas have a visible central dot with thin “legs” radiating outward, and pressing on the center causes the whole thing to blanch and then refill. Multiple spider angiomas are strongly associated with liver disease, with a specificity of 95% for chronic liver problems like cirrhosis. Cherry angiomas, the round red bumps without radiating legs, do not carry that association. If you’re unsure which type you have, a doctor can tell the difference quickly.
Telling Them Apart From Something Serious
Cherry angiomas are harmless, but not every small red bump on the skin is one. A rare form of melanoma called amelanotic melanoma can appear as a red or pink raised spot rather than the dark mole most people associate with skin cancer. The traditional “ABCD” screening criteria (asymmetry, border irregularity, color variation, diameter over 6mm) were designed for pigmented melanomas and can miss these red lesions entirely.
A more useful set of warning signs for red spots is what some dermatologists call the “3 Rs”: a red, raised lesion with recent change. A cherry angioma typically appears and then stays stable in color and shape for years. If a red bump is growing noticeably, changing shape, bleeding without being scratched, or looks different from your other cherry angiomas (the “ugly duckling” sign), it’s reasonable to have it checked. When there’s any uncertainty, a biopsy can rule out something more serious.
Removal Options if They Bother You
Because cherry angiomas are benign, removal is purely cosmetic. A systematic review of treatment options found that both laser and non-laser methods work well, and no single approach proved clearly superior to the others.
- Pulsed dye laser (PDL) is often preferred because it tends to cause less pain during the procedure. However, it carries some risk of pigment changes in people with darker skin tones.
- Nd:YAG laser produces fewer pigment-related side effects, making it a better choice for darker skin.
- Cryotherapy (freezing with liquid nitrogen) is quick and widely available but can also cause temporary lightening or darkening of the treated area.
- Electrosurgery uses a small electrical current to destroy the vessel. It’s effective and common in general dermatology offices.
Most cherry angiomas can be removed in a single session, and recovery is minimal, typically a small scab that heals within a week or two. Removing them doesn’t prevent new ones from forming elsewhere, so people who are bothered by the appearance often return periodically for touch-ups as new ones develop.
