They can invade the bowel and cause inflammation that accelerate colorectal tumor formation.

它们能入侵肠道，引发炎症并加速结直肠肿瘤的形成。

So this means that with more ovulatory cycles there's an increased risk of tumor formation.

这意味着排卵次数越多，肿瘤形成的风险就越大。

Each time cells divide, there is a chance of a mutation and the possibility of tumor formation.

细胞每分裂一次，就有突变和形成肿瘤的机会。

Each time cells divide there's a chance that a genetic mutation will occur and a mutation can lead to tumor formation.

每次细胞分裂都有可能发生基因突变，而突变就可能会导致肿瘤的形成。

This process could potentially lead to uncontrolled growth and tumor formation.

这个过程可能会导致不受控制的生长和肿瘤形成。

Each time cells divide there is a chance of a mutation and the possibility of tumor formation, and this means that with more ovulatory cycles, there's increased risk of tumor formation.

每一次细胞分裂时都有细胞突变的可能，同时也增加了肿瘤形成的可能性，而这也意味着排卵期的循环提高了癌变的风险。
