Answer:

Most likely diagnosis is Basal Cell Carcinoma (BCC), most likely caused by years of prolonged exposure to sunlight over time.

Explanation:

Basal Cell Carcinoma (BCC) is a common type of skin cancer that develops when the basal cells that is responsible for producing new skin cells when they die, become mutated and causes the basal cell to abnormally multiply rapidly and continues to grow. The accumulation of these abnormal cells is what results  in cancerous tumors that appears like ulcers on the skin. Prolong and intense exposure to the ultraviolet (UV) radiation from sunlight has been linked to the most likely cause for the mutation of the DNA in the basal cells which leads the abnormal cell growth and multiplication. People who expose themselves to the radiation of the sun for longer periods, over time, are at high risk of developing this cancer.

Fungicide are primarily applied to an area to kill off fungi species in that place.

Fungi are very important groups of organisms. They are natural "recyclers".

In a food chain or web they can be classified as decomposers.

Decomposers are organisms that takes feeds on dead and decaying organic matter.

The produce useful materials and releases nutrients from life back into nature.
