Of all the cancers, skin cancer is the most common cancer in the United States. Fortunately, most skin cancers are visible, can be diagnosed and successfully removed before they spread to other parts of the body. Also, many lesions can be detected and treated at a pre-cancerous stage.

All people, regardless of skin colors and races, can get skin cancer. Those with light skin who sunburn easily have the highest risk. Risk factors include: sunburns, family history of skin cancer, exposure to X-rays and a weakened immune system. Additionally, using indoor tanning beds greatly increases the risk of developing skin cancer. It is important to know the facts about skin cancer and skin cancer stages in order to protect yourself from the disease.

There are 3 common types of skin cancer, and 1 type of pre-cancer:

Actinic Keratosis

Actinic keratosis (AK) is the most common type of precancerous skin lesion. An AK is evidence that sun damage has occurred and that the individual is at greater risk of developing skin cancer. AKs normally occur on the face, lips, ears, scalp, neck, back of the hands, shoulders, forearms and back, as these are the parts of the body that are most often exposed to the sun. When on the lip, they are called Actinic Cheilitis. AKs usually appear as small crusty, scaly or crumbly bumps or horns ranging in size from 1 mm to 1 inch. They are dry and rough to the touch and can be raw or sensitive. If AKs are treated early, they can almost always be completely removed before turning into skin cancer.


However, if left untreated, AKs may develop into squamous cell carcinoma, a common form of skin cancer in Los Angeles.

Basal Cell Carcinoma

Basal cell carcinoma (BCC) is the most common type of skin cancer. In most cases it appears on skin that gets a lot of sun, such as the face, scalp, neck, hands, and arms. BCC generally is a skin bump or growth that is pearly or waxy and is normally flesh colored or light pink. Basal skin cancer grows slowly and usually does not spread to other parts of the body. But it should still be treated promptly. Treatment of basal cell skin cancer varies depending on the size, depth and location of the lesion.

Squamous Cell Carcinoma

Squamous cell carcinoma (SCC) is the second most common type of skin cancer. This form of skin cancer arises in the squamous cells that make up most of the skin’s upper layers (epidermis). It tends to form on skin that gets frequent sun exposure including the rim of the ear, face, neck and arms. Anyone who has had a basal cell carcinoma is also more likely to develop squamous skin cancer. This skin cancer looks like a firm bump, scaly patch or an ulcer that heals and then re-opens, and is usually red in color. They often look like warts and sometimes appear as open sores with a raised border and a crusted surface. SCCs detected at an early stage and removed promptly are usually curable and cause minimal damage. However, left untreated, they eventually penetrate the underlying tissues and can potentially spread to lymph nodes and other parts of the body. Treatment of SCC varies depending on the size, depth and location of the lesion.

Melanoma is the most serious form of skin cancer. If it is caught and treated early, it is almost always curable. Seeking the help of an experienced Los Angeles dermatologist is always a great way to ensure you're getting the help that you need. However, if it is not caught early on it becomes hard to treat and can be fatal. Fair-skinned individuals with light hair and eye color have an increased risk of developing melanoma. Additionally, those who have a family history of the disease or have ever had skin melanoma or other skin cancer are at greater risk.


This skin cancer generally develops in a mole or appears suddenly as a new dark spot on the skin. Growths that change noticeably in size or have irregularities in shape and color could be melanomas. It is important to check your skin from head to toe regularly for lesions that have the ABCDEs of melanoma symptoms.
