Radioactive cancer patients attending this weekend's Super Bowl in Miami could be in for an alarming experience when they pass through radiation detectors designed to signal the presence of dirty bombs. Such cancer patients -- who have received treatment using radioisotopes and still may have tiny amounts of radioactive material in their bodies -- may want to come armed with letters from their doctors explaining their precarious set of circumstances.

The use of radioisotopes in medicine is growing -- and so is the use of radiation detectors in our security-conscious nation, which means patients are triggering alarms when they are not even aware they are being scanned, doctors and security officials say.

Nearly 60,000 people a day in the United States undergo treatment or tests that leave traces of radioactive material in their bodies, according to the Society of Nuclear Medicine. These traces are not enough to hurt anyone, but they are enough to trigger radiation alarms for up to three months.

Radioisotopes are commonly used to diagnose and treat certain cancers and thyroid disorders, to analyze heart function, and to scan bones and lungs. And many doctors already know to equip their patients with travel cards because of the problems they can encounter in public places.

Nearly 20 million nuclear medical procedures were performed in the United States in 2005 -- up 15 percent from 2001. Clearly, the number of people who could be mistaken for terrorists is quite large. So if you are one of these people -- with the power to create a buzz in a public setting -- get your papers in order so you can quickly confirm your identity as nothing more than a cancer patient.

Inflammatory breast cancer accounts for only 1 percent of all breast cancers -- yet this disease that mostly affects young women and teenagers can be especially aggressive. And sadly, many of the symptoms  -- inflammation, irritation, itching, redness, blotching, and increase in size -- are mistaken for infection. Not until further, more serious symptoms arise does breast cancer become a possible explanation. A breast may become firmer, warmer, and may grow in size more each day. Although distinct lumps are not apparent, the skin may become dimpled and increased tenderness can occur. Large veins may surface, and cancer may spread in sheets or nests instead of from a solid tumor -- making it virtually impossible to detect a lump. While mammograms are usually ineffective for detecting this cancer, certain biopsies and MRI testing can reveal and confirm a diagnosis -- which years ago was much scarier than it is today with new studies and research and therapies that can better fight this aggressive form of cancer.

A combination of the drugs Lapatinib and Capecitabine have been used to treat inflammatory breast cancer in women who have not responded to standard therapies. And this combination is doubling the patient's survival time. Like like the drug Herceptin -- used for many young women with another aggressive form of breast cancer -- these drugs may be the innovative new approach for saving even more young women.

Quick autopsies -- or rapid organ donation -- may steer scientists in the direction of better diagnosing and treating the most lethal of cancers. Some 33,700 Americans will be diagnosed with pancreatic cancer this year -- and 32,300 will die. There is no early detection test for this disease and early symptoms are vague and may be mistaken for health concerns like indigestion. By the time the classic symptoms -- jaundice and itching -- surface, the cancer has typically spread and patients have only months to live. Rapid autopsies have been used before -- for Alzheimer's and prostate cancer -- but this a first in the study of pancreatic cancer and it just may lead to the discovery of what makes this cancer so aggressive and so deadly.
