In some cases, the disease is more common than people think.
A recent study found that of more than 200 people with melanoma in England, half were found to have a very large abscess or abscess-like lesion.
This was even more common in the West Midlands and South East.
This is thought to be due to the fact that skin is more permeable and less resistant to infection.
It’s not the only type of skin cancer that grows in large quantities.
Others include skin cancers of the pancreas, liver and kidney, but it is the most common.
What causes it?
There are a number of possible causes.
There is evidence that the common bacteria living in the human gut, Candida, can cause skin cancer.
In a recent study, researchers in Sweden found that when Candida bacteria were isolated from human skin samples, they caused a 40 per cent increase in tumours.
A similar study from France found that Candida causes skin cancers in more than half of patients.
Another theory suggests that Candidiasis is caused by a fungus called Fusarium oxysporum.
This fungus is found in the mouth and can cause the condition Candidactylos.
Other fungi are also suspected.
This may be because the fungi are more likely to cause fungal infections in humans than in other animals, such as rabbits.
Other common causes of skin tumours include skin infections, trauma and smoking.
Another possible cause is that some people with skin cancers develop them later on.
The tumours may not appear until after a person has died of cancer.
These tumours often develop in the bone or in the fat of the head and neck.
Some tumours are so large they form a scar on the face.
This scar can take months to heal.
There may also be a secondary tumour in the upper arm, neck or breast, which is caused when a skin lesion is allowed to grow over it.
What are the symptoms?
As with most other skin cancers, it is not always easy to diagnose.
It is important to keep checking your skin regularly to make sure there is no sign of any other infections, such a abscess.
If you notice any unusual growths or other changes, ask your GP or dermatologist for an examination.
Some of the more common symptoms of skin cancers include: red, swollen, tender skin
