Sunburn, especially in childhood, is associated with a higher risk of skin cancers (basal cell carcinoma, melanoma and squamous cell carcinoma).

We should therefore all try not to get burnt in the sun and to be aware of the damage it can do to our skin. But some people need to be particularly careful. Individuals should be particularly careful about going out in the sun if they are:

  • Fair skinned or red head
  • Have lots of moles
  • Had a history of previous sunburn
  • Receiving chemotherapy
  • Have a close relative with skin cancer (melanoma)

On the other hand, regular sensible sun exposure is highly beneficial. 80% of our Vitamin D is formed in the skin during sun exposure. Vitamin D is essential for strong bones. It is an important anticancer agent. Clinical studies have shown that individuals who have regular sun exposure have a lower risk of bowel breast and prostate cancer. 

  Tip to avoid sun damage after cancer therapies

What to avoid:

 

Generally

Be sensible in the sun

Try not to get burnt

Do not sit in the sun when it is hottest - during noon and 3pm

Do not be temped to use sun-beds.

Stop smoking altogether Ė if you canít donít smoke whilst in the sun. The chemicals and carcinogens in the smoke greatly enhance the dangerous effects of sunlight.

During and after chemotherapy

During and shortly after chemotherapy the skin can be more sensitive to the sun.  All chemotherapy drugs can photosensitise the skin but particularly florouracil types drugs for bowel and breast cancer. (Sensitivity to chemotherapy agents usually wears off after three months)  

During and after radiotherapy

Be very careful with skin exposed to radiotherapy - Radiotherapy although better with modern techniques can damage the skin but only in the area specifically treated. This may be bigger than you think. For example, with breast cancer the upper cleavage area would have received a dose and this can have a high exposure to sun when wearing a v-shaped top.  Unlike chemotherapy, this sensitivity will be life long.

What to do more of:

 

 

Cover up with a hat, long sleeved shirt and trousers if you are out in the sun when it is hottest.

Wear a high factor sun screen and definitely a barrier cream on irradiated tissue

Gentle sun exposure late in the afternoon

After sun exposure liberally apply olive oil to all exposed areas for 10 minutes before taking a shower Ė watch you donít slip!
