internal Medicine, not calculated to destroy the Acidity of the Blood, but to dispose the whole _Cancerous Mass_, with its Appendices to come away, which might otherwise, as the Seeds of the Disease, cause it to spring again: Thus was this Patient, (after so great a Fatigue she had undergone before she came to me) perfectly cured, and has continued so to this Time, without any manner of Inconvenience as she lately told me, it being a long time since she has been well. A Gentlewoman near fifty Years of Age, by some Accident received a Blow on her left Breast, which in a few Days was succeeded by a considerable Tumour, whereupon she applyed herself to a _Surgeon_, who immediately let her Blood, ordered her to take the _Lap. Hibern._ in Posset-Drink, and embrocated the Breast with _Ol. Succini_: By the use of these Means the Swelling was much abated, a small Hardness only remaining, which did not exceed a small Wallnut in Bigness; in this State, with very little Pain, she continued above a Year; but being persuaded to apply an _Emp. de Ran. cum Mer._ to it, it encreased very apparently, was extreamly painful, and in Seven Months time became as big as a large Egg: After this she made use of a Woman who was reputed Famous for these Cases; but by One or Two of her Applications the Tumour became as big again as before: In short it continued to encrease gradually from that time, till the whole Breast, which was of a monstrous Bigness, and which was judged not to weigh less than Eight Pound, in time became entirely _Cancerous_. It was at this time that I saw it the Skin was very livid, looking sleek and shining, and seemed ready to open, as being scarce capable of longer containing such a prodigious hard _Mass_ as laid concealed under it, and was in all Probability as big as the Breasts of the _Ammonian_ Women, of which _Juvenal_ thus speaks, _In Meroe, crasso majorem Infante Mamillam_. She had been with various experienced and reputable _Surgeons_ before, among which was One not long ago deceased, who was justly looked upon as an Ornament of his Profession; but not one would willingly attempt a real Cure by cutting it off, or any other Way: They only prescribed some palliating Remedies to remove the Pain and prevent its Breaking. I was animated by my former Successes, and prevailed with my self to undertake it, not thinking I was at all blameable if my Success in so extraordinary an Affair contradicted the Prognosticks of so many worthy Gentlemen; and though it did, I shall at all times think my self obliged to pay a Deference to them. I began the Cure by removing the Integuments from the upper Part of the Cancerous Substance, but did not wait for a Separation of the Slough the Escarotick made for fear of being incommoded in my Procedure by a Fungus; For this Reason I mixed some of our Dissolvent with a digestive Ointment, by which Means I had a Part of the _Cancerous Mass_ came away with it, without any Trouble to my Patient.
