The common skin cancer that could turn into deadly melanoma- as President Joe Biden shows off sunburned skin on return from Caribbean vacation less than a year after having cancerous lesion removed

Joe Biden may have been put at increased risk of fatal skin cancer after getting sunburned during his New Year's holiday, experts say.

The 81-year-old president was pictured with “lobster red” skin on Tuesday as he returned from a week's holiday at a $3 million private villa in St Croix, the US Virgin Islands.

While a one-time sunburn is unlikely to develop into the deadly skin cancer melanoma, Biden has a history of cancerous lesions on his body — with repeated sunburn increasing the risk of several types of skin cancer.

In February 2023, the president had a lesion of basal cell carcinoma – a form of skin cancer – removed and has had several other bouts of the cancer before 2021.

Dr. Anisha Patel, a dermatologist at UT MD Anderson Cancer Center in Houston, warned that damage to the president's skin from the sun's rays increases the risk of melanoma — a skin cancer that only 30 percent of patients survive if detected at a late stage.

The president's sunburn was notable following his treatment for skin cancer in February 2023, during which he had a basal cell carcinoma removed from his chest

Speaking to DailyMail.com, she said: 'Sunburn increases the risk of skin cancer in general – including melanoma – due to exposure to UV radiation.

'The fact that he had basal cell carcinoma indicates that there is enough UV damage to cause skin cancer.'

However, she added: '(The fact) that he has not had melanoma so far is significant – and a good sign.

'As you get older, you are at increased risk of all forms of cancer because our DNA repair mechanisms do not work as well.

'So if he's made it this far without melanoma, his genetic risk factors are low. I see patients in their 20s, 30s and 40s with this skin cancer.”

Dr. Deborah Sarnoff, president of the Skin Cancer Foundation, told DailyMail.com that just five sunburns double the risk of developing melanoma.

And a 2023 study Research has shown that people who have had basal cell carcinoma have a sixfold increased risk of developing melanoma than those who have not had the disease.

Basal cell carcinoma is the most common type of skin cancer and the most common type of cancer in the US, with 5.4 million people diagnosed each year.

It usually develops in areas that are frequently exposed to the sun, where damage accumulates over time.

It occurs when cells in the top layer of the skin begin to divide uncontrollably, forming a translucent pink spot that may be itchy or painful.

Dermatologists treat the cancer through surgery to remove the growth, which is almost always successful. The cancer has a survival rate of more than 99 percent.

However, melanoma is a much less common form of cancer, accounting for approximately one percent of cases each year, and involves cells that produce pigment in the skin.

Like basal cell carcinoma, the risk of melanoma is also increased by sunburn, which can damage the DNA in the cells.

Warning signs of the disease include changes to an existing mole, such as turning red or changing shape.

If melanoma is detected at an early stage, almost all patients survive.

But if it is not discovered until it has spread to the lymph nodes, this drops to 72 percent of patients surviving five years after diagnosis.

If it is not discovered until it has reached another organ, only 32 percent of patients survive.

Biden was treated several times before 2021 for non-melanoma skin cancer – which also includes basal cell carcinoma. That's what the White House doctor saidadding that all cancerous spots were removed with clean margins.

He was also treated in February 2023 for a basal cell carcinoma on his chest, which was surgically removed.

His doctor said the surgery site was “healed well” and that the president would undergo routine checks of his skin for cancer.

People who have had basal cell carcinoma should see their dermatologist for check-ups every six to twelve months.

What is Basal Cell Carcinoma?

Basal cell carcinoma (BCC) is a form of non-melanoma skin cancer.

Non-melanoma means no skin pigment cells are involved.

BCC often appears as scabs that bleed

BCC is responsible for more than 80 percent of all skin cancers in the UK and US.

About 5.4 million basal and squamous cell cancers are diagnosed each year in the US and about 100,000 in Britain.

It is mainly caused by excessive exposure to UV light from the sun or tanning beds.

BCC can occur anywhere on the body, but is most common in sun-exposed areas such as the face, neck and ears.

The following people are most at risk:

• People with light skin or hair
• Those who work outside the home
• People who use tanning beds
• Those with a personal history of the condition

BCC is usually painless. Early symptoms often include only a scab that bleeds occasionally and does not heal.

Some look like flat, red, scaly spots or have a pearly edge. The latter can then erode into an ulcer.

Others are lumpy with shiny nodules with blood vessels running through them.

Most BCCs can be cured, but treatment is complex if they remain for a long time.

Treatment usually involves removing the cancerous tumor and some of the surrounding skin.
