REBELLIOUS.—In the case of cancer, heredity plays an extremely unimportant part. But there are certain families in which cancer seems to run as a family disease. You say your mother died of cancer, and that other relatives on your mother’s side have also died from that disease. How many of your relatives? Here it is a question of percentage. Cancer is a very common disease, and therefore the fact that two or three of your relatives have died of cancer may simply be a coincidence, and not a case of hereditary influence at all. As we see the case, we would not prohibit a woman from marrying because one or two of her relatives have died of cancer. If she is a member of one of the families in which cancer is the usual termination of its members, then the question must be looked at in another light. Still, even here we would not discourage marriage, for even in these cases the hereditary influence is doubtful. Where, however, the disease has been very rife, the woman must consider from a very wide standpoint whether she is justified in marrying and thus spreading this fearful disease; but in nine cases out of ten the answer will be “Yes, it is justifiable.” DONA ANNA.—We can quite understand your alarm when you found that you coughed up blood, and that you came to the conclusion that you had consumption is also not unnatural. But why did you not go to a doctor at the time? You say you had a bad cough at the time which kept you awake all night; but that you are not particularly subject to coughs, and that you have been perfectly well since. This subject of blood-spitting is very important, so we will briefly mention its chief causes. The blood may come from a tooth, from the gums, from the nose, or from the lips or tongue as a result of injury. It is frequently due to inflammation about the throat, especially of the tonsils. It occurs commonly in nearly all acute diseases of the lungs, especially in bronchitis and inflammation of the voice-box. These are the common causes. In all the amount of blood spat up is very small—usually merely streaks. In consumption and some forms of heart disease blood-spitting is common and is often very profuse. Other causes of profuse bleeding are the rupture of an aneurism and some diseases of the vessels of the lungs. Or the blood may come from the stomach. This is a formidable list, but we have no doubt whatever which of these caused your blood-spitting. It was acute bronchitis and not consumption.
