A pair of drugs can dramatically shrink and eliminate some breast cancers in just 11 days, UK doctors have shown. They said the “surprise” findings, reported at the European Breast Cancer Conference, could mean some women no longer need chemotherapy.
How long does chemo take to shrink tumors?
In general, chemotherapy can take about 3 to 6 months to complete. It may take more or less time, depending on the type of chemo and the stage of your condition. It’s also broken down into cycles, which last 2 to 6 weeks each.
Can a tumor shrink after one chemo treatment?
It can shrink a primary tumor, kill cancer cells that may have broken off the primary tumor, and stop cancer from spreading. But it doesn’t work for everyone. Some types of cancer are more resistant to chemo than others, and others can become resistant to it over time.
Does chemo shrink breast tumors?
Chemotherapy before surgery for breast cancer
Chemotherapy is sometimes given before surgery (known as neoadjuvant therapy or preoperative chemotherapy) to shrink larger cancers. This may: Allow the surgeon the best chance of removing the cancer completely.

How do you shrink a breast tumor?
Most often, these cancers are treated with neoadjuvant chemotherapy (before surgery). For HER2-positive tumors, the targeted drug trastuzumab (Herceptin) is given as well, sometimes along with pertuzumab (Perjeta). This may shrink the tumor enough for a woman to have breast-conserving surgery (BCS).
Do tumors bleed when they shrink?
Tumor bleed is commonly seen in locally progressive tumors, which have directly infiltrated blood vessels. However, tumor bleed secondary to rapid shrinkage has not been reported previously. We report on a patient who had a torrential bleed after initiation of multi-agent chemotherapy.
