"Abortion is an accepted medical procedure for terminating pregnancy. Amici medical organizations recognize the acceptability of abortion, as their policy statements indicate; they draw no distinction between abortion and other medical procedures. The Texas abortion law effectively denies Appellants Roe and Doe access to health care. Jane Roe was forced to bear a pregnancy to term though an abortion would have involved considerably less risk to her health. Physicians who would otherwise be willing to perform an abortion in clinical surroundings are deterred by the fear of prosecution. Since Appellant Roe could not afford to travel elsewhere to secure a safe abortion, to avoid continuation of pregnancy she would have been forced to resort to an unskilled layman and accept all the health hazards attendant to such a procedure. Even had she been able to travel out of state, the time required to make financial and travel arrangements would have entailed greater health risks inherent in later abortions."
