US Cancer Death rates have fallen between 1% and 2% each year since 1991.
The American Cancer Society has reported that US Cancer Death Rates have fallen between 1% and 2% each year since 1991. That is an overall decease of 27% since 1991.

I suspect that the trend will continue as Medical Cannabis becomes legal in more States. Why? It has been shown that THC Oil (made from Cannabis) can be an effective treatment protocol for some individuals and some Cancers. THC has been shown to kill cancer cells in lab studies. Human cases (not peer reviewed studies) have had THC inhibit the growth and metastasis of Lung Cancer for Example. THC Oil is credited with shrinking inoperable Brain Tumors is another example. As Cannabis becomes legal there, will be new Medical Studies done on it.
There is also another report which states that smoking in the US is at a record low. Fewer people smoking will result in fewer people getting Lung Cancer or Heart Disease and other complications due to smoking cigarettes. In the near future I will do a post on that report.
PSA Testing for Prostate Cancer made No Significant Difference in Prostate Cancer Deaths after 10 years.
A new study has been published Mar 06 2018, in the Peer-Reviewed Medical Journal called Journal of the American Medical Association (or JAMA). The Study found that PSA test screening did not achieve its aim of diagnosing fast-growing cancers in time to treat them and prevent Deaths.

Title: Effect of a Low-Intensity PSA-Based Screening Intervention on Prostate Cancer Mortality: The CAP Randomized Clinical Trial
Author: Martin, Richard M.; Donovan, Jenny L.
Publisher: American Medical Association
Date: Mar 6, 2018
There were men who were tested and the PSA Test found that they had a High PSA. Of those who agreed to further treatment during the study, some men were seriously harmed by treatment. There were 8 deaths in the screening group related to either the biopsy or prostate cancer treatment and 7 in the control group.

How effective is Chemotherapy as a treatment for Cancer?
Posted by Vincent Banial
Chemotherapy can be an effective treatment for Hodgkin’s disease (HD) – a type of lymphoma, which is a blood cancer. Chemotherapy can also be an effective form of treatment for Testicular Cancer.
What about other Cancers?
A study was published in the Dec 2004 issue of the Peer Reviewed Journal called Clinical Oncology, which addressed that question.
The following is taken from the abstract of that research Study :
“The overall contribution of curative and adjuvant cytotoxic chemotherapy to 5-year survival in adults was estimated to be 2.3% in Australia and 2.1% in the USA.”
The conclusion as found in the abstract was:
“it is clear that cytotoxic chemotherapy only makes a minor contribution to cancer survival. To justify the continued funding and availability of drugs used in cytotoxic chemotherapy, a rigorous evaluation of the cost-effectiveness and impact on quality of life is urgently required.”.
Found a link using a web search. The link is below ( you have to copy and paste the URL if you wish to visit their site – as you would from a web search):
Basically that is supposed to be a PDF of the results from that study published on Dec 2004 in Clinical Oncology. It lists over twenty different Cancers and the percentage increases in 5 year survival rates for those patients who received Chemotherapy treatment for said Cancer.
Clinical Oncology had also published another research study in November 2004. You can view an abstract at nature.com by clicking on this line.
The following was the conclusion of the Nov 2004 published in Nov 2004:
“Adjuvant chemotherapy after potentially curative surgery can improve 5-year survival by 4% in patients with early-stage non-small-cell lung cancer (NSCLC, stages IB–IIIA).”.
So after surgery, Chemotherapy may increase the 5 year survival rate in about 4% of the patients. Yes, only 4%.
Using the above quoted studies and being overly generous, in my opinion it may seem that Chemotherapy does not increase the 5 year Survival Rate for about 85% of patients with many forms of Cancer. The exception is that yes it may be a form of effective treatment for Hodgkin’s Disease and for the treatment of Testicular Cancer.
With some Cancers the study chart (see the link to the PDF above) shows Chemotherapy to have zero effect on 5 years Survival Rate.
That leaves the question: Why is Chemotherapy being given to Cancer patients?
