Below I have listed 20 plus documentedted references from medical journals. Read it and weep, and next time do some research before opening up our mouth about something you have no idea about.
Erickson, Milton H. Breast Development Possibly Influenced by Hypnosis. Two Instances and the Psychotherapeutic Results. American Journal of Clinical Hypnosis, 1960, 2, 157-159. See also The Collected Papers of Milton H. Erickson on Hypnosis, in E.L. Rossi (ed.), Hypnotic Alterations of Sensory, Perceptual and Psychophysical Processes. New York: Irvington Publishers, 1980. The journal articles by Erickson include fine measurements and process descriptions. Both simple suggestion imagery and analysis are found effective.
LeCron, Leslie M. Breast Development Through Hypnotic Suggestion. Journal of the American Society of Psychosomatic Dentistry and Medicine, 1969, 16, 58-61.
Elman, Dave. Elman reports in his audio recordings of trainings (1960s) he conducted for doctors that he had successfully worked with a number of women for breast enhancement. The method used was hypnoanalysis and results were typically two cup size increase.
Peter H.C. Mutke, M.D. (UCLA) performed the first study. He presented his results as a research paper to the Department of Neuropsychiatry, University of California, Los Angeles, February 28, 1971. As of 1994, Dr Mutke was still with UCLA and has been active in the American Council of Hypnotist Examiners.
Williams, J.E., Stimulation of Breast Growth by Hypnosis. Journal of Sex Research, 1974, 10(4):316-326. His thirteen volunteers averaged 2.11 inch increase in the circumference of their breasts (2 cup sizes). (Method = age regression and age progression).

Staib, A.are., and Logan, D.are., Hypnotic Stimulation of Breast Growth. The American Journal of Clinical Hypnosis, 1977, 4:201-208. They repeated Dr. Williams' protocol with similar results. They also found women's waist size decreased by 1.4 inches. Their follow-up study showed that 81 % of the breast enlargement was retained several months after the women stopped their visual imagery. (Method = Williams + general health/vitality)
Willard, are. D., Breast Enlargement through Visual Imagery and Hypnosis. The American Journal of Clinical Hypnosis, 1977, 4:195-200. Dr Willard used a different technique than Dr. Williams (who used age regression and age progression) and achieved an average 1.44 inch increase in breast size for his 22 volunteers. Every woman had an increase in their breast circumference. (Method: Direct suggestion, rational framework for belief)
Excerpt of the RESULTS section of the Willard study:
At the end of 12 weeks, 28% had reached the goal they had set at the beginning of the program and desired no further enlargement. There were 85% who could tell a significant enlargement in their breasts had been accomplished, and 46% found it necessary to buy a larger brassiere. Forty-two percent had a loss in weight of greater than 4 pounds and still had enlargement of their breasts. The average increase in circumference was 1.37 inches; the average increase in the vertical measurement was 0.67 inches and the average increase in horizontal measurement was 1.01 inches.... [note: the study was continued past 12 weeks to let those who hadn't reach their goals to do so].
In this study, 63% of the subjects had had children and complained of pendulous breasts. These subjects expressed a desire to reclaim the fullness and contour of the breasts which they had before the pregnancies. All of these subjects reported they were very pleased with the increase in fullness and firmness of their breasts at the end of the study.... The only two subjects who subjectively felt there had been no significant increase, did have a measurable increase in size. Both subjects had difficulty obtaining the visualizations. All of the subjects reported an increase in firmness of their breasts. All of the subjects who began the study with one breast smaller than the other found them to be equal in size at the end of the twelve weeks.
Wilson, Donald L. MD, Natural Bust Enlargement with Total Mind Power: How to Use the Other 90% of Your Brain to Increase the Size of Your Breasts. 1979 Book. Has the scripts and a great bibliography. Dr Wilson ran a clinic in California with great success. This book (a small hardback) is available through Hypnosis Institute of Texas.
Beran, Roy (a neurologist at Adelaide Children's Hospital, England) presented the results of his study to the February 1979 National Convention of Hypnotherapists in Adelaide. Dr. Beran showed that the breast volume (he measured the breast's cubic displacement of water) more than doubled during the three-month hypnosis program.
Friesen, Wendi. Hypnotic Breast Enhancement, 1998. Also does work with adapting hypnotic techniques to penis enlargement in men. Friesen uses general visualization, age regression, stimulation, timeline, and trigger response conditioning.
Body Beautiful magazine in the UK reports on the case of a 32 year old woman who uses hypnosis to go from a 32A to a 32C in a period of six months.
Phillips, Brian David. Hypnobreasts: Hypnotic Language and Guided Imagery for Breasts and Body Image, 2001. Part of a pilot study on imagery and breast enhancement. The program uses trigger response conditioning supplementing general visualization, age regression, stimulation, and timeline visualization. Participants had best results with weekly hypnosis sessions supplemented by listening to a brief recorded session daily. The trigger-response exercise was very helpful for most participants. Results were very successful with an average increase of two to three cup sizes for most of the women participating in the study.
In 2002, the BBC investigated researchers at the University of California who were conducting trials on breast increases. They found the results were very positive. Other studies have shown similar results dating back to the 1960's. Results are often seen of increases of at least one cup size. In one study of over 800 women, 80% saw gains of over one and a half inches in breast size.
Kein, Gerry. Hypnotic Enhancement of Breasts, Omni Hypnosis Center, 2003. Average increase of one to two inches and one cup size. The general procedure outlined involved direct suggestion (Direct Drive), age regression to puberty, imagination and future pacing desired results. Kein says that only in a small/limited number of cases you have to do some regression to cause to remove any blockages.
William Henningsen outlines the following criteria for breast enhancement programs: Create a compelling future and link it to an every day activity of theirs (for reinforcement, Towards Propulsion). Create an anchor of pleasurable or desired feelings for completing the daily exercises of listening to the recorded induction. Make the act of doing the exercises reinforce the compelling future image. Link their 'away from' criteria to not doing the exercises. (Away From Propulsion)
