Raised Skin Bumps
Raised skin bumps can result from a number of conditions, benign
or harmful, but in most cases they are harmless. An infection, an allergic
reaction, a hereditary condition, or even skin cancer can cause bumps to form
on your skin.
Skin bumps can vary in appearance depending on the cause. They may be skin-colored
or discolored. They may be itchy or not itchy, large or small, multiple or
single. Some are hard while others feel soft and movable. Most bumps need no
treatment unless they cause you discomfort. If you are concerned about any
changes in the condition of your skin, you should see your doctor.
Causes and Types of Raised Skin Bumps
are many different conditions that can cause raised bumps to appear on your
skin. The most common causes of bumps are harmless and do not require medical treatment
unless you have discomfort:
- Cysts are growths that develop
under the skin. They feel like a small ball and can be moved around slightly.
- Angiomas are blood vessels that
collect together and create a raised, reddish spot on or bump under the skin.
- Seborrheic keratosis are round spots on the
skin that appear most often in middle age. They may be skin-colored, brown, or
- Moles are flat or raised bumps
on the skin that are usually benign and range from skin-colored to dark brown.
- Acne causes skin bumps that
can range from very small to bigger and painful. The bumps are usually
accompanied by redness and swelling.
- Lipomas are collections of fatty
tissue under the skin and are often painless.
- Corns or calluses, usually on the feet, are
rough, thickened areas of skin.
- Allergic eczema is an allergic skin
reaction that produces redness, itching, and irritation.
- Psoriasis is a skin disease that
produces scaly, red, inflamed patches on your skin that may be itchy.
- Keloids are smooth, raised
growths that form around wounds.
- Keratosis pilaris is a skin condition
characterized by overgrowth of a protein called keratin. It causes small bumps
around hair follicles on the body.
- Skin tags are small, fleshy flaps
of skin. They usually grow on the neck or armpits.
- Mollusca are bumps in the groin
area that are usually small and flesh colored. They arise from sexually
transmitted diseases, but usually disappear after a couple of years.
- Warts, which are caused by a
virus, are raised, rough bumps, usually on the hands and feet.
- Cold sores are bumps around the
mouth that are caused by the herpes virus.
- Boils are infected hair
follicles that are not life-threatening, but often require treatment to heal.
- Insect stings and bites are often itchy and
swollen. They may cause pain that lingers.
Less commonly, raised skin bumps are caused by
conditions that require treatment. Certain bacterial and viral infections cause
bumps and will only worsen without a diagnosis and treatment:
- Staphylococcus aureus (MRSA)
- scarlet fever
- genital herpes
- genital warts
Another type of skin bump to be concerned about is
that caused by skin cancer. There are several types of skin cancer, all
- Basal cell carcinoma appears on sun-exposed
skin and produces pain and bleeding in the early stages. The associated bumps
may be discolored, shiny, or scar-like.
- Actinic keratosis is a precancerous
formation that appears as a scaly or crusty bump on the skin. You will be more
likely to feel it than to see it.
- Squamous cell carcinoma is a type of skin cancer
that often starts as actinic keratosis. It may be crusty, pink in color, and
raised above the skin.
- Melanoma is the most serious type
of skin cancer and begins as an atypical mole. Cancerous moles are often
asymmetric, multi-colored, large, and has irregular borders.
Treatment for Raised Skin Bumps
for skin bumps depends on the underlying cause. In most cases, you will need no
treatment, but you should see your doctor if you are uncomfortable, you don’t
know the cause of the bumps, or you suspect skin cancer or an infection.
bumps that are harmless and need no treatment can be removed for cosmetic
reasons. For instance, your dermatologist can freeze skin tags or warts to
remove them. You can have cysts or lipomas removed surgically. Other bumps that
are itchy or irritated may be treated with topical ointments.
your skin bumps are caused by an infection, your doctor will recommend a
treatment plan. For a bacterial infection, like MRSA or syphilis, you may need
a course of antibiotics. Some viral infections cannot be cured, like herpes.
However, your doctor can give you medications to treat the symptoms.
any bumps in which cancer is a possibility, your doctor will perform a physical
examination, and then remove a sample for a biopsy. The biopsy can show you if
the bump is cancerous or precancerous. If it is only precancerous, your doctor
will most likely remove it completely and then check the spot from time to
Long-Term Outlook for Raised Skin Bumps
most skin bumps, the long-term outlook is excellent. The majority of bumps are
caused by benign, often temporary conditions. In the instance that you have an
infection, treatment should either clear it up, or effectively treat the
symptoms. If you catch a patch of skin cancer early, your prognosis is good with
treatment, but you will require follow-ups to be sure it does not return. The
outlook for more advanced forms of cancer varies with each individual
