Summary: 
			Teenagers are most vulnerable and negatively impacted by abortion 
			and hormonal contraception. 
			
			At a time when 
			their breasts are already growing, induced abortion alters their 
			physiology in a way that results in a much higher risk of subsequent 
			breast cancer.
			
			
			By choosing 
				abortion, a woman increases her risk of breast cancer in four 
				ways: 
			
				- 
				
				
				she creates in her breasts more places for cancers to 
				start, which is the “independent effect”;  
- 
				
				
				she loses the 
				protective effect that a full-term pregnancy would have afforded 
				her;  
- 
				
				
				she increases the risk of premature delivery of future 
				pregnancies, 
				thus losing the benefit to breast cells that a full-term 
				pregnancy gives; and 
				 
- 
				
				
				she lengthens her susceptibility window.  
				 
			
			Following abortion, many teen women take hormonal contraceptives 
				that in most circumstances can elevate the risk of breast cancer 
				even more.  Contraceptives containing estrogen-progestin 
				drugs increase breast-cancer risks by causing breast cells to 
				proliferate increasing the chance of mutations leading to cancer 
				cells, and by acting as direct carcinogens.
