While most cancer research is funded by drug companies with the aim of increasing their profits, there are now also a growing number of independent studies that show the negative side of conventional cancer therapy. Here is a small selection of interesting research findings.

Conflict of Interest in Cancer Research: This analysis shows why it is so difficult to get to the truth in medical research. Conflicts of interest exist in a considerable number of cancer research articles published in medical journals, and there is a high degree of financial connections between researchers and pharmaceutical companies. This produces biased results with a more favorable outcome for investigated drugs and technologies [1].

Experts want to stop screening: Screening for breast and prostate cancer has not brought a decline in deaths from these diseases. Instead screening programs lead to tumor over-detection and over-treatment [2].

Morphine stimulates cancer and shortens life: Morphine has been used in cancer treatment for two centuries. Now research shows that it stimulates the growth and spread of cancer cells and shortens the survival time of patients [3].

Diagnostic X-rays cause cancer: It has been estimated that diagnostic X-rays over a lifetime cause up to 3.2% additional cancers in a population. Germany ranks among the countries with the highest X-ray cancer rates while with 0.6% the U.K. and Poland have the lowest lifetime risk, in Australia it is 1.3% [4].

Radiation therapy damages bones: The scientific world has been shaken by a report that a single therapeutic dose of radiation can cause appreciable bone loss. Years later osteoporosis, bone necrosis or bone cancer may develop [5].

More radiation danger: Exposure to ionizing radiation is known to result in genetic damage that can make cells cancerous. Now a new study has revealed that radiation can alter the environment surrounding cells so that future cells are more likely to become cancerous [6].

Chemotherapy promotes metastasis: Taxol, a chemotherapy drug, causes cancer cell micro-tentacles to grow longer and tumor cells to reattach faster. If treated with taxol before surgery to shrink the primary tumor, levels of circulating tumor cells go up 1,000 to 10,000 fold, potentially increasing metastasis [7].

Tamoxifen increases aggressive tumors: Tamoxifen use for breast cancer patients decreases their risk of developing a more common and less dangerous type of second breast cancer but has a more than four-fold increased risk of causing a more aggressive and deadly tumor [8].

Biopsies cause metastases: Biopsies may actively encourage the spread of metastases. Needle biopsies caused a 50% increase of metastatic spread to nearby lymph glands of breast tumors as compared to lumpectomies [9].

Stress promotes cancer: Stress hormones protect cancer cells from self destruction, promote the spread and growth of tumors directly as well as indirectly by weakening the immune system and encouraging new blood vessel growth. Patient stress  was associated with faster disease progression [10].

Stress kills: Stress hormones are released in high amounts with fear and during surgery. They greatly impair the immune system and promote the spread of metastases. Blocking stress hormones increased long-term post-operative cancer survival rates in animal models by 200-300 percent [11].

Breast cancer metastasis after hormone replacement therapy: Previously it had been shown that hormone replacement therapy increases the risk of breast cancer. Now a new study has found that it also increases the chance of the cancer metastasizing, or spreading to the lymph nodes [12].

Sharp drop in breast cancer rates: In recent years breast cancer rates dropped sharply due to a corresponding sharp drop in the use of hormone replacement therapy [13].
