Prevention of cancer. Is it possible?

Is it possible to prevent cancer by making life style changes? This question just crossed my mind and I immediatedly Googled. The answer was a very clear yes. That is, it is possible to decrease the risk of cancer in people who are at high risk for cancer. It is also possible to reduce the complications and prolong life after cancer treatment. Best of all, many of the required life style changes are simple and doable. At a quick glance, these are most noted life style changes:

- Healthy diet: at least five portions of fruits and vegetables per day (one portion = 80 grams). High fiber.  Whole grains. Less red meat. Less saturated fats. Less salt and sugar. Less processed food.
- Active life style. Exercise.
- Keep good weight. Obesity is a risk factor.
- Avoid smoking. Avoid tobacco.
- Be mindful of your alcohol intake i.e. keep it low or avoid.
- Take special measures to reduce exposure to UV radiation.
- Reduce exposure to pesticides and environmental pollutants.

Fact: 40% of cancer incidences are preventable. More than 50% of cancer-related deaths can be prevented. These are facts backed by abundant literature evidence.

In the context of dietary interventions for preventing or potentially even treating cancer, Dr. William Li gave an impressive TED talk about his work on anti-angiogenesis therapy for cancer and foods that can starve angiogenesis (http://www.ted.com/talks/william_li?language=en).

Chetta idea - 1

Alternative title: proposal for a health care project. Diseases such as hypertension (high blood pressure), diabetes, obesity are becoming so common nowadays. It is hard to find people with no diseases. The lifestyle is certainly to be blamed. But what is the use if we just shut our mouth after finding the right thing to blame? Or how would I be different if I leave it there. So, here is a proposal for an automatic health-care system. Well, I know there maybe some treatments, but the idea here is to prevent the diseases. But, prevention really demands prediction of the disease occurrance much before the disease symptoms show off. But, since I am not a palmist or an astrologist, my proposal is to develop a method to stop the disease as soon as its onset or the symptoms appear. OK... it will become more clear as I go with the concrete examples. I would like to concentrate on hypertension and diabetes, because they appear to be the most common diseases. As most of you know, the best cure

ZyXEL VMG3326 D20A ADSL modem Linux wireless network problem

I bought 10Mbps ADSL network connection from Saunalahti . It works all perfect except for this little glitch I had with it: from my Linux Mint Debian Edition (LMDE) or Ubuntu machine, I could not get the wireless network. While a windows machine and two android phones can access the wifi signals from the modem, the Linux machines can't even see the SSID of my network. In the beginning when I had just setup the modem I could access the wireless network from my LMDE machine. I started noticing the problem with the network, when I turned off my ADSL modem one day and in the evening turned it on. While all other machines got the connection as soon as the modem was up, my Linux machine could not detect the signal. After a little bit of messing around, I concluded that, for Linux to receive the wireless signal without a problem and to get the connection after the modem restarts, I need to follow the following protocol. I need to turn the wifi off on the modem by pressing a blue butto

Installation of ATI catalyst propreitary driver on LMDE (Linux Mint Debian Edition)

Google turns up many posts explaining how to install the ATI catalyst proprietary drivers on LMDE. Take this post as just an additional information. In my case, the installation did not work until I accidentally installed another package, x11-xserver-utils.  Thus, in my case, the installation of the drivers was as follows: sudo apt-get install x11-xserver-utils sudo apt-get remove --purge fglrx* sudo apt-get update && sudo apt-get install fglrx-driver fglrx-control sudo /usr/bin/aticonfig --initial sudo reboot I think the reason it worked this way was because computer couldn't recognize the correct graphic device version before the installation of x11-xserver-utils.
