Re-evaluating the Benefits of Cancer Screening
uncleO writes "An article in the NY Times describes two studies that weigh the harm caused by cancer screenings against the benefits they provide. From the article, 'Two recent clinical trials of prostate cancer screening cast doubt on whether many lives — or any — are saved. And it said that screening often leads to what can be disabling treatments for men whose cancer otherwise would never have harmed them. A new analysis of mammography concluded that while mammograms find cancer in 138,000 women each year, as many as 120,000 to 134,000 of those women either have cancers that are already lethal or have cancers that grow so slowly they do not need to be treated. ... In recent years, researchers have found that many, if not most, cancers are indolent. They grow very slowly or stop growing altogether. Some even regress and do not need to be treated — they are harmless."
We could break apart the back room collective bargaining and price fixing and actually make health care something that people actually pay for, like car insurance and automotive services. That way, at least, we can see some competition for price and maybe people will even understand the resources they waste every time they go to the doctor about a cold. (Well, at least after they paid $80 to hear the doc say "It's a cold, drink some juice and get some rest" they'll think twice before doing it again.)
This is a common fallacy -- that the costs of going to doctors for minor discretionary ailments are a significant part of health care costs. As the economist Paul Krugman has explained, the major expenses in health care aren't $80 visits to the doctor, but $50,000 and $100,000 cancers, $20,000 a year lifelong treatments for diabetes, $50,000 a year lifelong treatments for multiple sclerosis, $50,000 and $100,000 heart bypass operations.
Actually, there have been many studies over at least 40 years to see whether charging patients more would produce better -- or even cheaper -- care. They all failed. Look up the Rand Health Insurance Experiment in Wikipedia. Patients who had greater copayments put off necessary care, like blood pressure medication (probably the most cost-efficient intervention we have).
U.S. corporations like IBM tried imposing co-payments on their employees, and they ended those policies when they found that they wound up spending *more* money. Patients with asthma put off maintenance care, and wound up going to the hospital more.
Health insurance isn't like car insurance. If your car is damaged, you know what the problem is and you know what's going on. If your doctor tells you that you have a disease you never heard of, and that you have to treat it right away, you don't know what's going on. It will take you more than a day of Google searches to find out.
If a nurse tells you, "You should go to the hospital right away. It could be life-threatening," what are you going to do? Look it up on the Internet?
Making health care decisions is like a graduate-level exam with questions you're unlikely to understand, and if you get one question wrong, you die.
It would also help the problems with cancer screening: once people see a $10,000+ price tag on treating that maybe-dangerous tumor they'll definitely give waiting and seeing a thought.
Ridiculous. The main thing a cancer patient wants to know is whether (or how long) he's going to live. The only concern about treating a tumor is (1) whether it really is a tumor that has to be treated and (2) what the best treatment is.
Cancer chemotherapy causes heart failure and other cancers. Is the risk of death from treatment greater than the risk of death from no treatment? Nobody takes doxorubicin just because they can get it free.
I know people who are doing watchful waiting, because their doctors think it's one of those false positives. I've talked about the decisions with them.
$10,000 doesn't enter into the decision. How much is your life worth?
