My main frustration is the fear of cancer from low dose radiation, even by radiologists.

The growth of technology is such that it is not possible today for a nuclear physicist to switch into medical physics without training. The field is now much more technical. More training is needed to do the job.

I have the satisfaction of knowing I did something useful for society.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

When I entered the field in July 1958 I believed what they told me about radiation risks. I spent much effort reducing the dose to patients in radiology.

Medical physicists work in cooperation with doctors. A few medical physicists devote their time to research and teaching. A few get involved with administrative duties.

Too many radiologists still believe there is a risk from a chest x-ray. Few radiologists can explain radiation to the patient in words the patient can understand.

I am now almost certain that we need more radiation for better health.

I was the Chair of the first department of medical physics in a medical school in the U.S.

There are now over 5,000 medical physicists in the U.S more than 50 times the number in 1958.

Many Nobel Prizes are awaiting good research to understand and explain the many mysteries of our bodies, such as the basic mechanism of memory or imagination.

In 1970 I realized that there was negligible risk from x-rays but many radiographs had poor image quality so that the risk from a false negative was significant.

I would not encourage everyone to take up this profession. Not everyone is suited for any particular field.

We developed simple test tools to optimize imaging parameters. No company was interested in our idea.

If someone is interested in medicine and also in physics and they like working with people and communicate well with others, I would strongly encourage them.

I have devoted much time and energy to helping medical physics in developing countries.

I am sure that I have been much more useful to society as a medical physicist.

In some cases radiation reduces the incidence of cancer.

I am not unhappy that my contribution was not recognized. I am sure it helped my career.

I don't display my plaques and honors. They are hidden behind a black curtain in my work room at home.

Nuclear physics is interesting but it is unlikely to help society.

Medical physics is an applied area of physics.

I found collaborating with congenial doctors about problems that physicists could help solve was very satisfying. I also like educating anybody who would listen!

It is likely that we need more radiation to improve our longevity.

My main frustration is the fear of cancer from low dose radiation, even by radiologists.

I started the nuclear medicine laboratory at UW Hospitals in 1959 and trained radiology residents in the field. It was 1965 before they found a trained MD (doctor) to take over my role.

When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.

Cancer can take away all of my physical abilities. It cannot touch my mind, it cannot touch my heart, and it cannot touch my soul.

Cancer is just a horrible disease.

I think suicide is sort of like cancer was 50 years ago. People don't want to talk about it, they don't want to know about it. People are frightened of it, and they don't understand, when actually these issues are medically treatable.

Most medical physicists work in the physics of radiation oncology making sure that the desired dose is given to the cancer and the dose to normal tissues are minimized.

I'll also tell you that five hundred thousand people will die this year of cancer. And I'll also tell you that one in every four will be afflicted with this disease, and yet, somehow, we seem to have put it in a little bit of the background.

I applaud the American Cancer Society for all they do to eradicate smoking. Their local, state and national efforts help to discourage young people from taking up this deadly habit and the resources they provide have helped numerous smokers quit.

Cancer, like any other illness, is a bore.

Cancer victims who don't accept their fate, who don't learn to live with it, will only destroy what little time they have left.

Breast cancer is not just a disease that strikes at women. It strikes at the very heart of who we are as women: how others perceive us, how we perceive ourselves, how we live, work and raise our families-or whether we do these things at all.

In terms of fitness and battling through cancer, exercise helps you stay strong physically and mentally.

If you're unable to catch it in time, the cancer can spread to the lymph nodes and at that point, the cancer is essentially incurable, but that doesn't mean your condition can't be improved.

Understanding how DNA transmits all it knows about cancer, physics, dreaming and love will keep man searching for some time.

I recently formed a foundation to raise awareness for prostate cancer. I feel it's very necessary that men be more aware about prostate cancer and their health in general.

Time is shortening. But every day that I challenge this cancer and survive is a victory for me.

In too many cases, the moms, the dads, the sisters and brothers of children with cancer must stand by a hospital bed and watch helplessly as this horrible disease consumes the life of an innocent child.

Cancer has been unfortunately in my life. My mom's best friend is kicking ass in her battle with breast cancer. Both of my grandmas had cancer. I recently lost a friend to cancer.

I do a lot of races for the cure for breast cancer.

This show has shown me how to throw a punch. But watching my future sister-in-law go through breast cancer has also shown me how to take one.

I don't think makeup is rocket science or a cure for cancer.

Germany has reduced savagery to a science, and this great war for the victorious peace of justice must go on until the German cancer is cut clean out of the world body.

All the things that human beings suffer from are how their environment treats them, and how the elements of their planet affects their mind and body - like radiation, cancer, and all.

New drugs and surgical techniques offer promise in the fight against cancer, Alzheimer's, tuberculosis, AIDS, and a host of other life-threatening diseases. Animal research has been, and continues to be, fundamental to advancements in medicine.
