Along the pike comes a new product designed to send us an alert when we've had too much sun.

Think about this:

There are some fun and fancy bracelets on the market that change color when it's time to seek shade.

UV Sol Beads, made with UV-detective pony beads and a removable fashion bead, feature off-white beads that remain off-white whenever there is an absence of UV light. When exposed to UV light, the intensity of the beads' color increases as the amount of exposure increases.

I hadn't been on an airplane since 2001. So all of the customs and rituals of airport safety were entirely new to me. I had no idea I 'd be told to remove my shoes before walking through the security contraption or that my baggage would be opened, searched, and inspected. It was a whole new world for me. Prior to 2001, none of these security measures were necessary. A compression sleeve wasn't either.

A compression sleeve -- my own personal security device -- is my new travel companion. Designed to protect my arm from swelling caused by the combination of missing lymph nodes and airplane cabin pressure, this sleeve fits my arm from wrist to armpit. It's tight like a glove and while it's not a very apparent fashion statement, it's slightly visible with its darker-than-flesh color.

I almost forgot to wear my sleeve on my flight to Tucson because I sometimes forget about breast cancer and it's effect on my life still. I sometimes forget how unsafe this world can be too. Then I see barefoot travelers passing through an airport corridor just before a jolt sparks my memory, and I rush to pull on my sleeve before it's too late.

There are four missing lymph nodes up my sleeve. And I must never forget this.

I never would have predicted it -- that a tooth could become a tool for dispensing medication. But the refinement of such a creation is actually in the works and before long, you may be asking not for a gold or decorative tooth but for one capable of doling out your drugs in the exact doses and at the right times.

Think about this:

Researchers from Europe and Israel are working right now on a tiny dispensing system called IntelliDrug. Their goal is to create parts small enough they can fit into a false tooth placed in the back of the mouth. The device will release a specific amount of medication at certain intervals so patients receive the proper dosage right on schedule.

This invention, crafted by an Israeli dentist, could pick up the slack for people who forget to take medicine and could save lives for those whose lives depend on scheduled drug therapy. It could also allow for better absorption of medication into the body.

The IntelliDrug device will deliver medicine directly into the bloodstream through the lining of the cheek around the mouth. Saliva, meanwhile, mixes with the drug and carries it throughout they body in a manner more efficient than just swallowing a pill every few hours.

While researchers hope to one day turn their device into a replacement tooth, the apparatus -- consisting of a stainless steel housing, a pump, custom valves, a microprocessor, batteries, and a reservoir for the drug pill -- currently comes in the form of a block the size of two teeth. It is strapped to the the side of teeth and hugs the inside of the cheek. The unit can be removed, and a technician can refill the drug reservoir, clean the unit, and change batteries when necessary.

Clinical trials on pigs are ongoing. Human testing is expected to begin by the end of the year.

There are four pages in the March 2007 Reader's Digest featuring amazing discoveries, devices, tests, and cures. And many of the snippets of information are -- yes -- somehow linked to cancer.

Think about this:

• A new ultrasound technique lets radiologists distinguish between malignant and benign breast lesions. Using elasticity imaging, researchers accurately identified harmless and cancerous lesions in almost all of the 80 cases studied. If results can be reproduced in a large trial, this technique could significantly reduce the number of breast biopsies required.

• Scientists seeking new treatment for diseases can use an online tool developed by researchers at MIT and Harvard. The Connectivity Map matches diseases with compatible drugs, based on the genetic profiles of both. So far, about 160 drugs and compounds are cataloged, and a few new uses for existing drugs have already been suggested. Eventually, all FDA-approved drugs will be included.

• For those who sometimes forget to take their pills, a new device -- that can be preloaded with up to 100 doses of medication -- could one day be implanted in the body and programmed to administer drugs via wireless signals. This device, successful in tests using dogs, was designed to deliver medicines that are less effective when taken orally.

Sometimes it seems cancer's grip is tightening. Other times, in the war against this pesky disease, it seems we are on the verge of something really great.

Early trials show a breath test for lung cancer detection may surface in the not-too-distant future. And it could be simple, inexpensive, non-invasive, and effective too.

The tests needs a good amount of work still, but if we keep our fingers crossed and medical researchers stay hot on the trail of this test, it just might be possible to one day spot lung cancer by simply breathing into a device for a few minutes.

The lung cancer breath test measures chemicals called volatile organic compounds (VOCs) in the breath. There's a certain pattern of VOCs associated with lung cancer, and they show up as colored dots across a quarter-sized panel.

The theory behind this test is great. The test itself is not perfect yet, however.

It's promising, though, says The Cleveland Clinic's Peter Mazzone, MD, MPH and colleagues who describe the test in the Online First edition of the journal Thorax and reveal the test correctly identified in studies three out of four people with lung cancer and detected lung cancer almost as frequently.

The National Institutes of Health (NIH) has awarded Techniscan Medical Systems (TMS), a Utah-based company that has developed an ultrasound imaging system known as UltraSound CTTM, a $2.8 million dollar small business grant to go forward with a radiation-free, non-invasive, breast cancer screening device that does not compress the breast during examination.

How does it work? While a woman is lying face down, the breast is suspended in warm water and an ultrasound scanner rotates in a circle, producing detailed 3-D images. According to the company, the diagnostic imaging tool will be able to detect normal, benign and malignant tissues in the breast.

The Australian is reporting that Australian researcher Professor Christobel Saunders has been awarded the 2006 Novel Concept Award by the National Breast Cancer Foundation to research the development of a breath test device to detect breast cancer.

"Previous studies have found that in women with breast cancer these VOCs are significantly and specifically altered, providing a marker which can indicate the presence, and also importantly the lack, of breast cancer in patients," Professor Saunders said. "Considering some of the downsides of mammograms, including the pain and discomfort experienced by a few patients and the number of false positive findings, which can result in needless anxiety and biopsies, this device has the potential to be used in conjunction with existing screening procedures, increasing the accuracy of diagnosis."

In addition, State University of New York at Buffalo researchers are building the breathalyzer device, a pocket-sized portable chemical sensor that will test a person's breath to detect cancer and a team of researchers at the University of Michigan won a Breast Cancer Research Program Idea award to develop a portable device to test breath for the presence of metabolites associated with breast cancer. Previous studies have proven human breath from the body changes when disease is present.

Danny became aware of my port just before it was removed. He was only 18 months old when I was diagnosed with breast cancer, and my journey went pretty much unnoticed by this small boy who had no idea ports were not standard on every person he met. Now he is three years old and even though he still has no real idea why a port popped up from underneath my skin for two years, he did come to realize it was something akin to a boo-boo that one day goes away.

My port went away on September 15. And ever since that day, Danny has been very concerned about the incision that marks the spot once home to a foreign device. For one week after my port removal, my incision was covered. Danny wondered why. I told him I was healing, that I had to keep my boo-boo protected, that I could not take a shower because it could not get wet. Danny was very attentive. He pulled at the neck of my shirt every time I held him to sneak a peak at the site of my surgery. He asked if it hurt, if doctors cut me with a knife, if new skin was growing underneath my bandage. "Yes", "yes", and "yes." I told him. And one day when I decided to take a shower, despite orders to keep the area completely dry, Danny said, "The doctor said you cannot take a shower." I told him, "I know." And he said, "But actually you did take a shower." I told him he was right and hoped he would not pursue my disobedience any further. He did not -- he was just checking up on me, he was just concerned about me, he was just wondering if I may have compromised something. I told him I was fine.

I did not do any damage with my rebellious shower, my bandage is off, and Danny only peeks once in a while to monitor the area. He is mostly back to his normal life, free from all nursing duties. And I am mostly back to life, free from my port and happily showered in love by my littlest guy -- the guy who was once oblivious to all things cancer related, the guy who somehow became my caregiver.

NIRScanner is a battery-operated hand-held infrared-based optical scanning device that the developers claim is both affordable and safe and could be used by women as an at-home personal health care solution to the early detection of breast cancer.

However, Drexel University and the University of Pennsylvania scientists state the device is not designed to replace mammography, ultrasound, or other methods of screening for breast cancer, only that it offers an additional method of detection, much the same as monthly self-exams, only far more accurate at early detection. The simple device surpasses self-exam by touch in that it can detect changes in the breast that traditional self-exam could not, and the developers state that it would alert women to seek medical attention should the device detect a problem in the breast.

The NIRScanner makes steady low beeps as it moves over the breast. Using a type of near-infrared light that travels deep into breast tissue, if the hand-held device detects a tumor the beep tone gets higher. A microchip stores the information on the size and location of the tumor as the patient performs the self-examination and the information can be taken to be analyzed on a computer by a physician.

Although the researchers state that the device proved to be accurate over 90 percent of the time, it is still being tested, and needs funding to be brought to market. To read more about the NIRScanner, they have made an illustrated brochure available as a PDF document.

Herceptin -- a targeted breast cancer drug used to treat women who are Her2 positive -- has received rave reviews and has shown great promise in cutting down on recurrence of this aggressive form of breast cancer. Given over the course of 52 weeks, Herceptin is wondrous for its lack of short-term side effects. There is no hair loss, no compromise of blood counts, no significant sickness. For me, fatigue may have resulted from this treatment -- but it's unclear to me really whether it was the Herceptin or the two small boys I have living in my house that most contributed to my occasional exhaustion. Regardless, I functioned well while receiving Herceptin for the past year -- and I did not suffer anything more than a twinge of pain when my port was accessed for each treatment. In the short term, I have fared well. In the long term, the jury is still out.

Purdue University engineers are creating a wireless device the size of a grain of rice that will then be implanted in tumors for the delivery and tracking of cancer-fighting radiation. The dime-sized prototype, as shown in the photo, has been successfully tested and the researchers believe the smaller rice-sized version will be completed this year. The device will be activated with electrical coils placed next to the body.

According to Purdue engineer Babak Ziaie, "Currently, there is no way of knowing the exact dose of radiation received by a tumor. 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."

"This will be a radiation dosimeter plus a tracking device in the same capsule." Very cool. Perhaps one day they can stop the dynamite-fishing approach of current cancer treatment where healthy cells and tissue are destroyed in an attempt to destroy cancer cells and tumors. Then it will be welcome to the 21st century of medicine.
