Squamous and Basal Carcinoma Johnathan and Kayla Anatomy
Squamous and Basal Carcinoma Johnathan and Kayla
Anatomy of the integument that is affected? Squamous Cells • Flat outer layer that constantly sheds. • Least common 2/10 cases. Basal Cells • Constantly dividing to form new cells , as they move up to the outer layer they become flatter. • Most common 8/10 cases
What is wrong with the anatomy? • Discolored (usually red in color) • Sometimes shows up as a rash or bleeds • Large growths may itch or hurt Cancerous growths can spread if left untreated
Who is likely to be more affected? • • • Uv Lights from exposure to too much sun or tanning beds Light coloured skin Older age groups People who smoke Weakened immune system (HIV and Aids) Radiation exposure Scars or damaged tissue Chronic inflammation Psoriasis treatments Inherited DNA condition Chemical exposure (coal tar, arsenic)
How is it treated? Minor treatments • Excision: Is a treatment that cuts out the cancer spot and some healthy skin around it • Surgery using a small hand tool and an electronic needle to kill cancer cells • Mohs surgery (microscopically controlled surgery) An excision and then inspecting the excised skin using a microscope (a precise surgical technique used to treat skin cancer) • Lymph node surgery: remove a piece of the lymph node; uses general anesthesia • Topical chemotherapy: a gel or cream applied to the skin • Targeted drug treatment
What risk factors are associated with the disorder? • If left untreated it can spread to other parts of the body • Unlike other types of skin cancer, squamous cell skin cancer can spread to the tissues, bones, and nearby lymph nodes, where it may become hard to treat. When caught early, it’s easy to treat through minor treatments.
What can you do to prevent this disorder? • There is no sure way to prevent this condition. • Risk factors cannot be controlled (Age, gender and family history) • Limit your exposure to the sun • Not smoking • Avoid weakening your immune system • Check skin regularly • Avoid harsh chemicals to your skin • Avoid indoor tanning beds/tanning lotions • Use sun screen
How is the disorder acquired? • This disorder can be acquired through genetics (Inherited through DNA). • Actinic keratosis-is also known as solar keratosis is a pre-cancerous skin condition caused by too much sun exposure. • Both are common with sun exposed skin, but squamous cell carcinoma is more visible to the eye.
