The following Observation contains an Account of one that was cured of an incipient _Cancer_ in her Breast, by Internals. I was the rather inclined to set down the whole Process of this Cure, because by these, or such like Medicines, Persons under the same Circumstances may perhaps be cured, though by some they may be thought incurable. The Case is this; A Gentlewoman, Thirty Years of Age, of a thin spare Habit of Body, by some Accident received a Blow upon One of her Breasts, which put her to an immediate Pain, and that very acute; but it lessened upon her being let Blood, and the Application of a discutient Plaister: However, in a few Days, some of the glandulous Grains of the Breast became indurated, and in Process of Time, by their Increase, they were rendered painful. At this Time she sought out for fresh Advice, and continued Two Months under the Care of a Person she was recommended to; but Things not succeeding according to Expectation, she became a Patient to Three or Four more. During this Time the Lump continued to encrease but slowly, and at the Expiration of Six Months it appeared to be a very hard painful Tumour in the Middle of the Breast, but no bigger than a Hen-Egg; whereupon it was thought proper to commence her Method of Cure by exhibiting the following _Pills_. ℞ _Pill. Tartar. Quercetan._ ʒß. _Calomel_ gr. viii. _F. Pill._ N^{o.} 5. These were likewise continued twice a Week during the whole Cure; after this, was ordered the following Infusion, ℞ _Vin. Rhenan._ ℔ii. _Milleped._ ℥ii. _Ocul. Canc._ ℥ß _Croci._ ʒii. This was not to be taken alone, but when it had stood Four and Twenty Hours, three or four Spoons-full of it was to be mixed with a Draught of the ensuing Dietetick-Drink, and taken in the Morning, and at Four of the Clock in the Afternoon. ℞ _Rad. Sarsaparill._ ℥ii. _Chinæ_ ʒvi. _Fig. Sassafr._ ℥i. _Corn. Cervi_, ℥_Sem. Correand._ ℥ß. _Sant. Rub._ ʒii. _Coq. in aq. Font. Congiis 4 per Horæ dimidium, deinde stent Clause super Cineres Calidos per Horas_ xii; _postea ebulliant ad tertiæ Partis Consumptionem_. By the Continuance of these Means about two Months, and observing a regular Method of living, the Cure of this Patient was effected; though by some she had been looked upon as incurable, unless she would submit the cutting it out, which is not often attended with Success.
