Hello and thanks for your enquiry,

Some skin lesions can certainly change or progress to then be described as tumours or a cancer.

It is completely understandable that you feel frustrated by the clinical language. The term "lesion" is simply a medical catch all word used to describe any area of abnormal skin tissue, regardless of size or cause.

An actinic keratosis (AK) is a superficial skin lesion. However, as Squamous Cell Carcinoma (SCC) cells grow, they form a distinct, physical mass of tissue. By definition, a mass or abnormal growth of cells is called a tumour or a cancer. The rapid growth and "erupting" appearance you mention is seen with SCC growths.

Yes, a weeping area can be a risk for infection. The clear or light yellow fluid is serous exudate. While it can be a natural byproduct of a growing, ulcerating skin cancer, it signifies that the protective outer skin barrier has broken down, leaving the area vulnerable to bacteria. Given that your surgery is four weeks away, protecting this delicate site is important.

Pause the hair dryer as directing warm or cool air onto a raw, weeping tumour can cause the tissue to dry out too harshly, form vulnerable cracks, or inadvertently blast environmental bacteria directly onto the open wound. Switch to gently patting the surrounding scalp dry with a clean, freshly laundered towel or sterile gauze.

Continue your daily showers to keep the general area clean, but avoid letting a high-pressure shower stream hit the growths directly. Do not scrub or rub the site. Use a mild, unperfumed soap or simply let lukewarm water rinse over it. Do not apply over-the-counter antibiotic creams, petroleum jelly, or heavy dressings unless explicitly instructed by your GP/pharmacist or hospital medical team, as these can trap bacteria or irritate the surrounding skin.

Do seek advice from your GP Practice nurse, or a local pharmacist. They can advise on what skin dressing can be used, or skin products, at this time. You may be able to seek advice from the hospital, if you do have any contact details for a dermatology clinic nurse.

I hope that this helps,

Best wishes,
