Encouraging fact from cancer statistics

Click For Summary

Discussion Overview

The discussion revolves around cancer statistics, specifically the decrease in cancer death rates in the United States since 1975. Participants explore the implications of these statistics, potential contributing factors, and the broader context of cancer mortality in relation to other diseases.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant notes a 21.9% decrease in cancer death rates in the U.S. since 1975, with a 15% decrease from 2007 to 2017.
  • Another participant questions the extent to which the decline in cancer deaths is attributable to reduced smoking rates, suggesting that improvements in treating other diseases may lead to an increase in cancer deaths as life expectancy rises.
  • A later reply acknowledges the role of declining smoking rates but also points out that other cancers not linked to smoking are also declining due to improved treatments.
  • One participant expresses gratitude for advancements in cancer treatments over the past two decades and raises a concern about potential lung cancer risks related to indoor exercise during the pandemic, specifically regarding radon exposure.

Areas of Agreement / Disagreement

Participants express differing views on the factors contributing to the decrease in cancer death rates, with some attributing it to smoking cessation while others highlight the role of improved treatments and the complex interplay with other diseases. The discussion remains unresolved regarding the primary causes of the observed trends.

Contextual Notes

Participants acknowledge that cancer death rates are influenced by various factors, including lifestyle changes and advancements in medical treatments, but do not reach a consensus on the relative impact of these factors.

We study cancer to get better at killing it. And here is an enouraging detail:
Since 1975, the cancer death rate in the United States has decreased by 21.9% with a 15% decrease from 2007 to 2017. (https://seer.cancer.gov/csr/1975_2017)

Wonder how much of that is simply attributable to the decline in smoking? Problem is these death rates don’t exist in isolation - so on one level improvements in treating other diseases that kill older people - like heart disease or diabetes will lead to an increase in cancer deaths, as everyone has to eventually die of something. You see this in developing countries as basic medical care and life expectancy improves, cancer deaths increase

You're right that the decline in cigarette smoking is a large part of it, but these plots from the American Cancer Society show that other cancers not associated with smoking are declining as well as treatments improve.

Indeed. We have better cancer treatments today than even 20 years ago. That's something I'm grateful for when I consider cancer as a whole.

Related to lung cancer, I wonder if my friends that have moved their exercise routines indoors into a basement, due to the pandemic, will be at a higher risk of lung cancer due to radon. I think they should test before moving their cardio equipment to the basement.
