###Human: Can an endometrial polyp grow so quickly in a span of eight weeks? ###Assistant: Hi. From the ultrasound picture (attachment removed to protect patient identity) you have provided, it does not look like polyp in endometrium. In fact it looks like some collection such as fluid or blood in endometrial cavity, although the appearance of single static film can be deceiving. Polyp normally looks more hyperechoic (whitish). Even if it is polyp, there is no need to worry as many polyps come and go with menstrual bleeding and as you said there is 96% chance of it not being cancer. I always like to look on positive side. So, there is no need to hurry for hysteroscopy. Chance of polyp being endometrial cancer is very low especially if it occurs after abortion or childbirth as your endometrium had more than sufficient exposure to progesterone to prevent cancer. If you are feeling physically fit to carry pregnancy and of course if hemoglobin has come back to normal, there is no contraindication for conception. But, my recommendation would be to wait for at least one more month. If polyp is seen again in next midcycle scan, we can plan hysteroscopy in future and there is no need to think about it right now.
