Vanessa Carlton undergoes surgery as a result of ectopic pregnancy

It was a sad day for Vanessa Carlton, who had to announce the cancelation of her tour after an emergency surgery resulting from an ectopic pregnancy.

An ectopic pregnancy, according to the Mayo Clinic, is any pregnancy in which the fertilization and attachment of the embryo takes place outside the uterus. In most cases, this occurs within the fallopian tubes.

This was the unfortunate case for Carlton, who required emergency treatment to protect her own health after the pregnancy took hold in her right fallopian tube. Ectopic pregnancies such as this one present the risk of tubal rupture and internal bleeding for the mother. In cases like these, the embryo is considered unviable and women often have to undergo invasive surgery practices to remove the embryo before it can develop too far.

Because doctors caught the condition early, Carlton decided to undergo chemotherapy, rather than invasive surgery. However, despite doctors' best efforts, Carlton's tube began to rupture, causing her to need emergency surgery. Her entire right fallopian tube was removed as a result.

Carlton reported being sad to lose the pregnancy as a result of the ectopic pregnancy and following procedures. She's also dealing with intense nerve pain from the surgical site, which is keeping her off the stage at the present time.

"I was all set to fly to Vancouver on Wednesday but … I need to stay close to my doctors and the hospital in case this initial pain turns into something more serious," said Carlton, according to New York Daily News. "Gimme a couple more days, I'll be ready. Thank you for all your support and understanding through this."
