Dr. Deborah Lang: What is Skin Cancer?

In this episode, Therese Markow and Dr. Deborah Lang discuss the rise of skin cancer, particularly melanoma, and its causes. Dr. Lang explains that skin cancers are derived from different skin cells: basal cell carcinoma and squamous cell carcinoma, both linked to UV exposure, and melanoma, which can be UV-independent and linked to genetic susceptibility. Dr. Lang emphasizes the importance of early detection and personalized medicine, noting that melanoma can metastasize early. She also highlights the role of genetic mutations in cancer development and the impact of funding cuts on cancer research.

Key Takeaways:

• There are three major types of skin cancer. About 80% are basal cell carcinomas.

• Because we are living longer, we have an increased chance of cancer. However, other reasons for increased skin cancer include increased UV exposure and tanning beds.

• We are all born with moles, but if you notice a change or have a lot (such as over 100), it is worth getting them checked out.

• Between 5 and 25 minutes of sun exposure per day is enough for your vitamin D production (less for lighter skin). However, sunlight has other benefits for your health and circadian rhythm.

"Melanomas are derived from a different type of cell - from cells that produce pigment called melanocytes. While this type of cancer is much rarer than basal cell carcinoma or squamous cell carcinoma, it is the most lethal type of skin cancer." — Dr. Deborah Lang
