Researchers from Harvard Medical School, Boston, and the Institute for Systems Biology, Seattle, have discovered that the remains of tumor cells killed by chemotherapy or other cancer treatments can actually stimulate tumor growth by inducing an inflammatory reaction. The study also reveals that a family of molecules called resolvins can suppress this unwanted inflammatory response, suggesting new ways to enhance the effectiveness of existing cancer therapies
Conventional, radiation- and drug-based cancer therapies aim to kill as many tumor cells as possible, but the debris left behind by dead and dying cancer cells can stimulate the production of proinflammatory cytokines, signaling molecules that are known to promote tumor growth.
“Dead and dying tumor cells are an underappreciated component of the tumor microenvironment that may promote tumor progression,” explained Charles N. Serhan, PhD, Director of the Center for Experimental Therapeutics and Reperfusion Injury at Brigham and Women's Hospital and Professor at Harvard Medical School. Serhan and colleagues therefore decided to investigate whether tumor cell debris can stimulate tumor growth.

Answer:
The correct option is : a. diameter
Explanation:
The Kirby–Bauer test or the disk diffusion test, is a method to determine the antibiotic sensitivity of the given bacteria. This test involves the use of antibiotic discs to determine the effect of antibiotics on the bacteria.
In this test, the wafers having antibiotics and the bacteria are placed on the agar plate and incubated. If the antibiotics present stops the growth of the bacteria, there will be an area around wafer with no bacterial growth, such an area is known as the zone of inhibition.
<u>The </u><u>diameter of this zone of inhibition</u><u> is measured to determine the </u><u>antibiotic sensitivity of the given bacteria</u><u>.</u>
