Back in 2002, photographs of a somewhat plump Jamie Lee Curtis appeared in many popular magazines. At the time, Curtis was just two years into pursuing sobriety and had gained upwards of 20 pounds. It appeared Curtis was flaunting her new look, perhaps even giving the public permission to be happy in their own skin. Not a bad thing, right?

It was a bad idea, says Curtis who now regrets communicating to the masses that letting yourself go is OK. Because it's not. Now fit and trim -- not skinny, just trim -- Curtis says in the July 2007 issue of Ladies Home Journal, "So I think what some people took from those photos was: Love yourself, no matter what. And the problem with this is: What if what you're doing is unhealthy?"

"And the problem is that how many of us are killing ourselves every day? Who here has high blood pressure and is still eating salt and French fries? Who has been told that her liver is enlarged and unless she stops drinking she's gonna end up with liver disease and/or need a liver transplant? We create senseless acts of violence against ourselves every day. And we live in this amnesia that we're not."

Leroy Sievers is a journalist who has spent a long career covering dozens of wars. He is accustomed to seeing other people die. But now, he is witnessing his own death. And on a recent NPR podcast, Sievers talks about how his doctors are trying to kill him by pumping poisonous chemotherapy drugs into his body. They haven't succeeded in killing him yet -- but they haven't cured him of cancer yet either.

Blogger Dalene Entenmann wrote about Sievers on July 3, 2006, pointing readers in the direction of his NPR blog My Cancer. Since her posting, Sievers has continued to reflect on his battle and on October 3, he shared an essay about chemotherapy -- the same essay he reads on the NPR poscast. He tells readers and listeners that nowadays he reports for chemotherapy every three weeks and sits for five or six hours while drugs sail through his veins. The drugs just keep coming -- and a vacation from this drug treatment is nowhere in sight. It's become a way of life for a man who is simply buying time. It is a changed life -- one he would happily live without.

Sievers, who thought he won the war against colon cancer and is now fighting brain and lung cancer, wakes each morning and feels pretty good -- as long as he stays in bed. When he gets up, the nausea begins and the tingling in his hands and feet begins. It takes him hours to get going, and eating is the last thing on his mind. But he takes pills that require food so giving up food is not an option. Sievers fights through debilitating fatigue each day, and no longer schedules anything in the morning. Mid-day -- when he feels pretty good -- is when he packs in appointments and meetings. But it all wipes him out and by the end of the day, the nausea and fatigue is back. One-quarter of one day, and Sievers is totally spent. And then each evening is a repeat of each morning.

Sievers is trying a new drug and hopes it will shrink his tumor. He doesn't want to get his hopes up though, and he fears disappointment. Mostly, though, he wants his old life back. Even if just for a few days.

Chemotherapy is a good remedy for killing cancer cells -- and I hope every day that it did its job and killed all cancer cells that may have floated away from my original breast cancer tumor. But one not-so-good side effect of this good remedy is the beating that healthy cells take in the process of this life-saving treatment. It will be a red-letter day when chemotherapy can target only cancer cells, while leaving healthy cells unaffected. And this day may be a bit closer for patients in Taiwan who find they are in the early stages of relapse with nasopharynx cancer.

On Wednesday, National Taiwan University Hospital introduced a new high-tech laser procedure -- potassium-titanyl-phosphate or KPT -- to vaporize cancer cells. Doctors use a small endoscopic camera and easily manipulate the laser to precisely eliminate the cancer cells in the back of the nose and the soft roof of the mouth -- without harming healthy cells. The procedure takes roughly 90 minutes and requires a two-day stay in the hospital. This procedure should only be used in the early stages of relapse, though, and first-time cancer patients should still seek chemotherapy. And while those in later stages of relapse can still receive the treatment, it will only relieve discomfort without solving the problem.

To date, there have been 16 successful KPT treatments for this disease that about 1,000 people in Taiwan contract each year.

Say what you will about medicine or alternative therapies -- but I say research, research, research -- and look at everything with a critical eye and cynical perspective. Be determined but never allow yourself to become desparate about any situation you are faced with in life. Because it will keep you more safe than sorry. Here's a cautionary tale I want you to remember.

Thai authorities have arrested an Austrian man, claiming to be a doctor, accused of injecting terminally ill Australians, a New Zealander and other foreigners with bogus chemical cancer cures. Hellfried Sartori, 67, the quack of a doctor who was stripped of his medical license in the 90's and jailed several times in the states, is now being charged with fraud and practicing medicine without a license overseas.

How did the people who came to him to be injected with potentially lethal substances in hopes of curing cancer find him? On the internet! He advertised his ozone treatments on the internet. Not only did he advertise he could cure cancer, but according to investigators, the man said he could cure AIDS, allergies and hardening of the arteries.

According to a news report in the Bangkok Nation, one Australian cancer patient, Kathleen Preston, died last summer in a Thai hospital. An autopsy report found an excessive amount of potassium in her blood. Her death is under investigation.
