Good day.
I would suggest being proactive in the sense of doing all you can do
prevent any cancer. This one article maybe of interest to you. Good
luck and enjoy your day.

oman Bystrianyk, "Skin Cancer: Green leafy vegetables decreases risk;
dairy increases risk", Health Sentinel, June 4, 2006,
According to the Centers for Disease Control (CDC) the number of skin
cancer cases has increased in the United States with more than 1
million cases of basal cell or squamous cell cancer being diagnosed
annually. This number has greatly increased from 400,000 in 1980 and
600,000 in 1990. Squamous cell carcinoma (SCC) is the most common skin
cancer in white-skinned people and accounts for 20% of all deaths from
skin cancer.
Exposure to the ultraviolet (UV) rays from the sun is widely
considered to be the most important environmental factor in developing
skin cancer. UV radiation causes direct damage to the DNA and to the
immune system. UV radiation also causes indirect damage through the
formation of free radicals.
There has been evidence that diet could modify the risk SCC and other
cancers of the skin. Animal studies have shown that amount and type of
dietary fats promote skin cancer by altering the body's immune system
response to UV radiation. Other studies have shown that intake of
antioxidants such as selenium, vitamin C, vitamin E, and B-carotene
may provide protection against oxidative damage in the skin by
neutralizing free radicals formed by UV radiation.
Green leafy vegetables such as kale, spinach, and collard greens, are
known to contain a variety of vitamins and minerals and other
bioactive substances that may protect against cancer. These substances
include lutein, vitamins C and E, flavonoids, folic acid, and fiber.
Dark green leafy vegetables are rich in folic acid, which plays a key
role in DNA synthesis and repair.
A recent study in the International Journal of Cancer, examined the
association between food intake and the risk of SCC. The authors
studied over 1,000 adults living in Australia over an 11-year period.
Study participants were followed from February 1992 until December of
2002. Participants were provided full-body skin examinations as well
as detailed dietary food frequency questionnaire.
After adjusting for a variety of factors the authors found that
increasing intakes of green leafy vegetables were associated with a
significant decrease risk of SCC. "The highest tertile [one third of a
study participants] of intake of green leafy vegetables was associated
with a 41% decreased risk." However, intake of "unmodified" dairy (for
example, full-cream milk and cheese) was associated with an 84%
increased risk for SCC, although the results were considered non-
significant.
The authors also examined diet if any participant previously had skin
cancer. They found an even more substantial relationship. People who
previously had skin cancer had a 55% decrease in SCC with increasing
intakes of green leafy vegetables. Conversely, dairy showed a
significant 153% increased SCC risk. "Increased intake of unmodified
dairy products increased SCC risk by more than 2-fold."
The authors also found a non-significant protective effect in drinkers
of black tea in people who had no previous skin cancer. A previous
study had shown a significant protective effect of black tea
consumption on SCC risk. "Black tea contains theaflavins that have
been shown to scavenge oxygen species and inhibit UV-induced oxidative
DNA damage."
The authors conclude, "our findings show that higher intakes of green
leafy vegetables may help prevent SCC tumours among people who have
prior skin cancers, and that a high intake of unmodified dairy, such
as whole milk, cheese, and yogurt, may increase SCC risk in
susceptible individuals."

I had three skin cancer spots frozen last year. All three of the spots went
away after peeling. Now a spot has returned and seemed rough and dry. I
applied lotion for a few days and it looks a little better. I took one
picture before I used lotion and another picture two days later. Does this
look like skin cancer or dry skin?http://img.photobucket.com/albums/v87/will9198/c2.jpg

I'm worried. Thanks in advance for help and advice. I don't have health
insurance so I see a doctor at the health department that doesn't charge
very much. They usually charge $20 or $30 per visit. I could afford $100 or
$200 but I'm guessing a dematologist would cost a lot more.
