However, the response rate to even the most successful treatments is relatively low, with one recently trialled therapy showing strong effects in only around 10 per cent of prostate cancer patients.
A new study is shining light on breast cancer treatments.
According to first author Joseph Sparano of Montefiore Medical Center in Bronx, New York, "any woman with early stage breast cancer 75 or younger should have the test and discuss the results" with her doctor.

With women hardest hit by migraine headaches, Swiss drugmaker Novartis is gearing up its marketing message to counteract sexism that it worries might become a barrier to adoption of its new medicine Aimovig. In both groups 89% of women had survived the disease.
More than 20,000 women in the United Kingdom are diagnosed with hormone-receptor positive, HER2-negative, node-negative breast cancer annually. By finding, isolating and multiplying the tiny subset of immune cells that are still in the fight, then demonstrating their ability to vanquish a patient's tumors, Rosenberg's group has shown that "the cells are there", Mackall said. "As an oncologist, on Monday in the clinic, I will offer less chemotherapy that will not be of benefit to patients and that is very reassuring to know that when I am offering patients chemotherapy, they are likely to benefit from it".
An almost-unprecedented cure for a terminal breast cancer patient using a form of cellular immunotherapy shows that while immuno-oncology is still in its infancy, the potential is enormous.
The test examines 21 genes from a patient's breast cancer biopsy sample to determine how active they are.
But in recent years, as many doctors concluded that women with early-stage cancer were being over-treated, they have reduced their use of chemotherapy, which can cause nausea, fatigue and, in rare cases, more serious complications such as leukemia and heart failure.
"If confirmed in a larger study, it promises to further extend the reach of this T-cell therapy to a broader spectrum of cancers", said Tom Misteli, director of CCR at NCI. "Patients who had chemotherapy plus an anti- hormone pill versus an anti-hormone pill alone - they had no difference in terms of their survival or outcomes long-term".
A high recurrence score, above 25, means chemo is advised to ward off a recurrence, while a low score, below 10, means it is not.
Dr. Raymond says the study proves that chemo will hurt more than help women with low risk scores who are over 50. For women aged under 50 with scores of 16-25, there was some benefit in getting chemotherapy, but for those aged over 50 with scores under 25, or those aged under 50 and scores below 16, there was nothing to be gained from going through the draining process.
After tumor removal, genetic testing is commonly used to predict which type of chemotherapy would give the most benefit.
After enrolling for new trial in 2015, doctors in the U.S. adopted an experimental approach combining two different forms of immunotherapy after conventional hormone treatments and chemotherapy failed. Nine years after the treatment 94 percent of the women were alive and 84 percent were free from the cancer.
Doctors caring for Ms Perkins during her recovery described her return to health as "remarkable".
In the trial, more than 6,700 patients were split into two groups.
