Moles*-identification marks-are birth marks given by the God to most of the human beings. Unless and until U note any change in the size, color and asymmetric shape; nothing to be panicky. I'm 63+ “young” with all the organs intact and functioning up to optimum levels. I have more than 100 moles on my body, covering every organ, since birth. Prudent to take it easy and forget. As per Indian sentiment, a person with moles on gonads is blessed with lot of libido; which is totally satiated for life.
When the sun shines on bare skin, your body makes its own vitamin D. This is the major source of vitamin D, but it's not enough for many people. Fair-skinned people might get enough in 5-10 minutes on a sunny day, a few times a week. But cloudy days, the low light of winter, and the use of sun block (important to avoid skin cancer) all interfere. Older people and those with darker skin tones don’t make as much from sun exposure. Experts say it's better to rely on food and supplements. Tanning drives U towards melanoma, skin cancers, etc..
How to prevent Sunburn* & scope for consequential skin cancer, Melanoma, etc: Expose Ur body and or the affected parts within 90 minutes from sunrise & within 60 minutes before sunset. During strong winds, no exposure to sunlight, please. Any extra exposure shall be @ Ur own risk for skin cancer/melanoma..
Much before, it is too late, prudent* to see a general surgeon/local homeopath/dermatologist for physical examination, relevant investigations, accurate diagnosis and permanent cure by medication and or surgical interference. Much before the advent of super-specialties like nuero/pediatric/cardiac/renal/gynec/brai… gastro-enterology, and ENT etc., all these surgeries were conducted by general surgeons. Hence, a Surgeon’s approach is most appropriate and accurate. A good surgeon suggests cheapest and accurate diagnostic investigations only to ensure permanent cure.
