Answer

Brief Explanations:

Cancer is caused by mutations in a cell's DNA. Nicotine and tobacco contain carcinogens that can damage or change a cell's DNA, leading to uncontrolled cell - growth which is characteristic of cancer. Decreasing blood - sugar levels, increasing heart rate, and increasing phlegm and mucous production are not direct causes of cancer.

Answer:

by damaging or changing a cell's DNA
