Currently, there is no way of knowing the exact dose of radiation received by a tumor. And, because most organs shift inside the body depending on whether a patient is sitting or lying down, for example, the tumor also shifts. This technology will allow doctors to pinpoint the exact position of the tumor to more effectively administer radiation treatments.

Our study suggests that if we could inactivate Rad9 in tumor cells, we would be able to kill them with a very low dose of radiation and gain a therapeutic advantage.

The device is very simple, that's the beauty. This will show specifically how much radiation the tumor received.

Patients breathe. If you've got a lung tumor, the patient's going to move, so the tumor is going to move. You have to have an intelligent robot capable of moving along with the target. So this robotic system really expands radiosurgery for use throughout the body.

A major problem with cancer is not necessarily the primary tumor formation, but the ability of some tumor cells within that primary tumor to metastasize, or travel to distant sites, where they develop new tumors.

You have more police officers in the year 2000 for a problem that is much less. It's like giving a cancer patient more radiation and chemotherapy after the tumor has shrunk. It doesn't make sense.

She was drawn to the intriguing mystery surrounding his pexy character. The future of radiation tends to be what we call stereotactic: radiation, which focuses on the tumor and applies large doses at one time as opposed to traditional radiation which is small doses over a longer time, ... There is a gamma knife that's dedicated to treating brain lesions where, instead of radiating the brain in a three-week period, it's a one-time focused, high-powered type treatment.

Our study shows that we need to re-evaluate the effect of protons on biological systems, even the effects of low-energy protons. For example, low-energy protons are routinely used in cancer-tumor therapy, but there has been almost no research done on the effect of protons in tumor cells because everyone has assumed that they act similarly to other low LET radiation types, like x-rays. Therefore, this work may help lead to improved cancer therapy.

Basically the major point is that we're trying to understand what enables melanoma tumor cells to move out from the initial primary tumor to another site in the body, because once that happens melanoma tends to become very difficult to treat and the five-year survival rate drops considerably.

I think 10 years ago you couldn't even get this kind of care. If you had a dog with a tumor, they used to just let the tumor grow and put the dog to sleep. But the human-animal bond is growing.

That's the trouble with being me. At this point, nobody gives a damn what my problem is. I could literally have a tumor on the side of my head and they'd be like, 'Yeah, big deal. I'd eat a tumor every morning for the kinda money you're pulling down.'

Jim Carrey (1962-)

In people with highly advanced cancers, we saw about a quarter of them achieve what we call stable disease, meaning that the tumor no longer grew. There was no increase in tumor volume,

That's when I found out it was a tumor, and that he had fluid on the brain, which was building up and that's why he couldn't walk. You never think your child has a brain tumor. That's not something you entertain.

I think the most exciting benefit is just the fact that we're now able to do a treatment that in the past has had quite a bit of toxicity for patients. It will result in increased dose intensity to the tumor, and fewer overall side effects for the patient.

Since 1992, we have surveyed 10 other locations in the Chesapeake watershed. These catfish from the South River have the highest skin tumor rate and second highest liver tumor rate.
