A colon polyp is a small clump of cells that forms on the lining of the colon. Most colon polyps are harmless. But over time, some colon polyps can develop into colon cancer, which is often fatal when found in its later stages. Anyone can develop colon polyps. You're at higher risk if you're 50 or older, are overweight or a smoker, or have a personal or family history of colon polyps or colon cancer. Colon polyps often don't cause symptoms.
A pregnancy is divided into trimesters: 1  the first trimester is from week 1 to the end of week 12. 2  the second trimester is from week 13 to the end of week 26. 3  the third trimester is from week 27 to the end of the pregnancy.
Still, the trimesters of pregnancy can be a very useful âshorthandâ of sorts that we can use to talk about the symptoms and the progress of pregnancy. The first trimester starts with conception, and concludes roughly 13 or 14 weeks later. The second trimester begins when the first trimester of pregnancy ends. The second trimester of pregnancy begins at around 14 weeks of pregnancy. The second trimester will last for another 13 or 14 weeks, at which point the third trimester will begin. So, the second trimester encompasses the middle part of your pregnancy, and will lst from around the third month to around the sixth month of pregnancy.
