Quran protects women from cancer by the veil!!

Quran protects women from cancer by the veil!!
One of complicated problem in our different societies and cultures that contain different religions [Islam, Judaism, and Christianity] is wearing the veil and covering the whole skin of the body with appropriate clothes except face and hands which are permitted to be uncovered (as mentioned in Islam rules).
But the people who have another culture and religion consider that backwardness and reactionary.
Now, we want to discuss and explain that in scientific manner and ask question; what is the advantage of veil to women? Or why Islam has obligated the women to wear veil?
As known medically and anatomically, the body of women contains large amount of fatty tissue more than men. And our environment filled with harmful rays and damaged radiations. For example:
A- Non-ionized radiation:
1- Ultraviolet: although it has benefit actions but, may cause harm to body specially to skin and potentiate cancer.
2- Radio waves.
3- Micro waves.
4- Waves produced by mobile.
5- Low and very low frequency waves. And others
B- Ionized radiation:
1- Cosmic radiation: from universe.
2- Ionized food. And others
All these can cause direct Damage to DNA (molecules contain genetic information of cells) or indirect damage by reaction with fat components in body, and then produce free radical species that causes damage to nuclear components of cells.
We can see it in our world, since spreading of different forms of cancer specially breast cancer where the breast tissue is fatty and easy to affected by radiation.
But Quran spoke and warned us from this harm. In part 22, surah33: Al-Ahzab: (O prophet! Say to your wives and your daughters and the women of believers that they let down upon them their over-garments; this will be more proper, that they may be known, and thus they will not be given trouble; and Allah is forgiving and merciful).
Therefore, this fact stated in Quran before 14 century and God wants to prevent women to be commodity but, to be a valuable jewel given only to who deserves.
Unfortunately, we see in many countries the veiled women are assaulted them and called with backwardness and terrorism!!
Will become a human rights and protection of health from diseases reactionary!! How do you judge?!
