There are many different causes of bumps that appear on the skin. While many of these underlying causes do not result in serious complications, some cancers are associated with bumps appearing on the skin.

In this article, we look at the symptoms, diagnosis, and treatment of some of the most common causes of bumps on the skin.

A basal cell carcinoma may be caused by intense sun exposure.

Although it can be tempting to squeeze pimples, people should not squeeze papules as they do not have any pus inside of them, and squeezing can cause the skin to scar instead.

The best way to prevent papules is to follow good skin care. Wearing sunscreen may also help. As sun exposure can cause the skin to become inflamed, which can drive the development of papules.

To prevent getting actinic keratosis, basal cell carcinoma, melanoma, and other skin cancers, it is important to follow sun-safety habits. People should avoid direct sunlight for prolonged periods, especially between the hours of 10am and 4pm.

People are advised to apply 1 ounce of sunscreen with a sun protection factor (SPF) of 15 or higher to their entire body 30 minutes before going outside. Those who plan on being outside for a long time should use a broad spectrum sunscreen with an SPF of 30 or higher. A range of sunscreens is available for purchase online.

Tanning also increases risk for skin cancer, and people should never use ultraviolet tanning beds

Skin tags do not go away on their own. If someone has a skin tag that they want removed, they will need to see a doctor.

The removal process is quick and easy. Doctors can cut skin tags away with scissors or a sharp blade, and may use an electric cauterizing tool to prevent bleeding.

It is important to remember that skin tags do not normally cause medical problems and cannot become cancerous.

Doctors can normally diagnose skin tags easily by looking at them. However, if it is not obvious that a growth is a skin tag, a doctor may cut a portion of the growth away and send it to a laboratory to be tested. This is called a biopsy.

Basal cell carcinoma can only be diagnosed by a trained doctor. The appearance of the carcinoma can often resemble other skin conditions, such as psoriasis or eczema. The doctor will need to take a biopsy in order to diagnose basal cell carcinoma.

There are several different surgery options available for basal cell carcinoma. Radiation therapy and special light therapies are effective treatments. There are also some creams, gels, and solutions that can treat basal cell carcinoma.

Skin abnormalities that look black, change size or color, or bleed can be signs of melanoma, and so should be checked out by a doctor. New and unusual moles can also be a sign of melanoma, so it is important for these to be checked.

As with basal cell carcinoma, a biopsy will usually be taken to confirm whether or not a skin abnormality is melanoma. The usual treatment for melanoma is to surgically remove the tumor and some surrounding healthy tissue.

If untreated, actinic keratosis lesions can also rarely develop into skin cancer, so people should get these growths checked out by a doctor.
