Breast Cancer in a Patient under Levodopa Treatment

A case history of a patient who developed mammary cancer (T1N1bM0) after 5 ½ years of continuous treatment with Levodopa for Parkinson's disease is presented. The prolactin inhibition by the Levodopa was verified, and the clinical and mammographic growth, the doubling time, and the labeling index of the tumor were determined. The results were not significantly different than those obtained from patients with breast cancer not under treatment with Levodopa. The rapid growth and evolution of this tumor suggests that prolactin does not have an inducer or promoter effect in mammary cancer.

The Northwest Shelf area of Southwest New Mexico has had an exceptionally rapid growth as an oil producing province. The Anderson Ranch field, discovered by the Continental Oil Company in 1953, is one of the typically prolific oil fields in this Northwest Shelf area. This field (Figure 1) is the most southwesterly of a series of Devonian oil fields in the Northwest Shelf area of New Mexico. It is located 22 miles west of Lovington, New Mexico in sections 2 and 11, T. 16 S.‐R. 32 E., Lea County, New Mexico. The Anderson Ranch area was first found to be anomalous by a shallow oil well drilled in 1927 which found the Rustler Anhydrite unusually high. Core drilling carried out in 1940 developed an Anhydrite nose over the area. A reflection seismograph survey was carried out in the period from 1950 to 1951 which succeeded in mapping a closed anticline in the face of many difficulties in obtaining usable seismograms. It is believed that the seismic map prepared for the deepest horizon was caused by multiple reflections. The anticline so revealed was drilled in a unitized drilling program and a well was completed in the Devonian for an initial potential of 1,968 barrels of oil per day. This was the discovery well.

Experimental Scientist

Wide publicity has been given to the recommendation by an experimental scientist that mothers with a family history of breast cancer should not nurse their daughters for fear of increasing the child's risk of developing breast cancer.1 Because 5% of U.S. women develop this neoplasm,2 a substantial proportion of families have a member with breast cancer, and would be affected by the recommendation. The experimental basis for the advice against breast-feeding should be weighed against the epidemiological evidence concerning transmission of mammary cancer from mother to daughter. In particular, the risk of transmitting breast cancer to the child should be evaluated against the benefits derived from breast-feeding.
