Women’s Cancer Q&A: Advances in Care
WebMD’s women's cancer expert, Harold J. Burstein, talks to WebMD's chief medical editor about treatment advances, research breakthroughs, and the prognosis for the future.
Given these new targeted therapies, individualized treatment, and widespread screening, where do you think we’ll be in the near future? What about a cure for breast cancer?
I can tell you where I hope we are. As for a cure, people sometimes imagine
we’ll have a magic bullet or a super pill or some other treatment that will
make the cancer go away. So far that has proven elusive.
I think that, over the next few years and decades, we’ll continue to devise
even more specific, individualized treatments for each woman who is diagnosed
with breast cancer. That means that some women will have less treatment, some
We’ll also continue to make progress on treatments that have fewer side
effects. And I believe we’ll discover more about the risk factors for breast
cancer and the behavior of tumors -- both may lead to lower incidence.
Obviously, early detection is key, and that requires more sensitive tools
than we currently have. I’m hopeful that we’ll develop increasingly sensitive
techniques to catch breast cancer as early as possible.
Let’s move on to ovarian cancer, which is difficult to diagnose and therefore more deadly. What are researchers looking at right now in the fight against ovarian cancer?
You’re right. It has remained a more lethal cancer, for two reasons: One,
we’ve lacked good early detection, and two, new treatments have been slow to
develop. But we now know that giving chemotherapy drugs directly into the
lining of the abdomen means we can target more closely the source of the cancer
and also where it’s likely to spread. Emerging data also suggest that newer
drugs such as the antiangiogenesis drugs might be valuable for treating ovarian
cancer, so that’s an area of active clinical investigation. These drugs
essentially starve the cancer by blocking blood supply and depriving the cells
of oxygen and nutrients.
Of course, we now have a consensus on early ovarian cancer signs, which are
subtle and may not indicate cancer at all. The main value here is to raise
awareness of the disease and not to frighten women.
We still need a good tool to catch this cancer earlier. The National Cancer
Institute has been sponsoring early detection trials for ovarian (as well as
prostate and cervical) cancer for quite some time. Researchers are looking at
screening by ultrasound or by a specific blood test, so the results of these
trials could someday lead to earlier diagnosis.
