Women's height linked to ovarian cancer.

According to a review of studies, we can see that taller women have a slightly higher risk of ovarian cancer. International researchers say that there is a risk factor among women who have never taken HRT. In the past had some suggested a link, but there had conflicting evidence. In recent we can see the data of PLOS Medicine that in 14 countries, about 25,000 women with ovarian cancer and more than 80,000 women without ovarian cancer. Prof Valerie Beal of the Oxford University Epidemiology Unit told the BBC: "By
bringing together the worldwide evidence, it became clear that height is a risk factor." She also clear said that those women will be suffer, who had never taken HRT because there was a clear relationship between obesity and ovarian cancer.  She also added "Ovarian cancer can clearly be added to the list of cancers linked to obesity,"

Sarah Williams (the officer of health information at Cancer Research UK) said that body size was important for woman's risk of developing ovarian cancer.

She also said, "Women can reduce their risk of this and many other diseases by keeping to a healthy weight,"

"For women trying to lose weight, the best method is to eat healthily, eat smaller amounts and be more physically active."

But now days the reader in cancer epidemiology at the University of Cambridge name Dr Paul Pharaoh said that the increase in risk was small.

"If we compare a woman who is 5ft tall with a woman who is 5ft 6in tall, there is a relative difference in ovarian cancer risk of 23%.

"But the absolute risk difference is small. The shorter woman will have a lifetime risk of about 16-in-a-1000 which increases to 20-in-a-1000 for the taller woman.

"A similar difference in absolute risk would be seen when comparing a slim woman with a body mass index of 20 to a slightly overweight woman with a body mass index of 30."

Get ready for summer: Sunscreen versus sunblock
Do you know what sunscreen is? Dr. Udhay Sidhu from Apollo Hospital, Bangalore says, "A sunscreen is also referred to as a chemical sunscreen. It is absorbed into our skin and in return absorbs the UV radiation. It primarily absorbs UVB and only some of UVA. These are cosmetically more acceptable but may cause allergic reactions.

"What's in it: Your sunscreen is made up of chemical blockers like oxybenzone, avobenzone, and sulisobenzone.

Where does not it to do: The next time you shop for sun protection, Dr. Sidhu also says, "Avoid products with ingredients such as Para- aminobenzoic acid and parabens." These chemicals can cause redness, itchiness and other skin problems.

Do you know, what is sunblock? Dr. Sidhu says, "They provide protection against both ultraviolet A (UVA) and ultraviolet B (UVB) rays. They act by reflecting UV radiation before it touches the skin. These are also referred to as physical sunscreens. These tend to be greasy and thick on application, but cause very few allergic reactions."

What's in it: The ingredients to look for in your sunblock are titanium dioxide and zinc oxide, which are physical blockers

What you need: Dr. Sidhu also explains, "Look for products that mention Broad Spectrum (protects against UVA and UVB rays), water resistant sunscreen, with an SPF of at least 15. This should be used all year round on exposed skin. For fair skinned individuals with light colored hair it is preferable to apply sunscreen with a higher SPF."
