Cervical cancer tiny invasive cancer 1a1 metastasis chance is not high, but if not timely treated with the development will soon appear lymph node and distant metastasis. Cervical cancer is a common malignant tumor of the female reproductive system, which can be caused by many factors, such as human papillomavirus infection, unclean sex, etc. Stage 1a1 is the early stage of cervical cancer, representing invasive cancer, which can only be diagnosed by microscopy, with a measured depth of interstitial infiltration of <3mm. In this period, the lesion is limited and no metastasis has occurred. Most of them can be treated by radical surgical resection and can reach about 80% of five-year survival rate, with better overall prognosis. However, if you don’t cooperate with the doctor in time, lymph node metastasis and distant metastasis can occur in the middle and late stages of development, so patients need to actively cooperate with the treatment after diagnosis.
