"I was attracted to studies of cancer families because epidemiological studies show that virtually all cancers manifest a tendency to aggregate in families. Close relatives of a cancer patient are at increased risk of that neoplasm, and perhaps other forms of cancer. The excess site-specific cancer risk is exceptionally high for carriers of certain cancer genes, in whom the attack rate can approach 100 percent. In candidate cancer families, the possibility that clustering is on the basis of chance must be excluded through epidemiological studies that establish the presence of an excess cancer risk. Predisposed families are candidates for laboratory studies to identify the inherited susceptibility factors. These investigations have led to the identification and isolation of human cancer genes, the tumor suppressor genes. These cancer genes are among more than 200 single-gene traits associated with the development of cancer. Approximately a dozen inherited susceptibility genes have been definitively identified, and many more are being sought. From studies of retinoblastoma and other rare cancers, important new information was generated about the fundamental biology of cancers that arise in many patients. Isolation of an inherited cancer susceptibility gene provides opportunities for presymptomatic testing of at-risk relatives. However, testing of healthy individuals also raise important issues regarding informed consent, confidentiality and potential for adverse psychological, social and economic effects."

"Every creature, every work of God, is admirably well made; but if any one appears imperfect in our eyes, it does not belong to us to criticise it. Perhaps that which we do not find right in its kind, turns to our advantage, without our being able to perceive it. Let us look at the state of the heavens, one while the sun shines, another time it does not appear; now the weather is fine; again it is unpleasant; one day is hot, another is cold; another time it is rainy, snowy or cloudy; every thing is variable and inconstant. Let us look at the surface of the earth: here the ground is flat; there it is hilly and mountainous; in other places it is sandy; in others it is barren; and elsewhere it is productive. Let us, in thought, go into an orchard or forest. What do we see? Trees high or low, large or small, upright or crooked, fruitful or unfruitful. Let us look at the birds of the air, and at the fishes of the sea, nothing resembles another thing. Let us look at the beasts. We see among the same kinds some of different forms, of different dimensions, domestic or wild, harmless or ferocious, useful or useless, pleasing or hideous. Some are bred for men's sakes; some for their own pleasures and amusements; some are of no use to us. There are faults in their organization as well as in that of men. Those who are acquainted with the veterinary art, know this well; but as for us who have not made a study of this science, we seem not to discover or remark these faults. Let us now come to ourselves. Our intellectual faculties as well as our corporeal organization have their imperfections. There are faculties both of the mind and heart, which education improve; there are others which it does not correct. I class in this number, idiotism, imbecility, dulness. But nothing can correct the infirmities of the bodily organization, such as deafness, blindness, lameness, palsy, crookedness, ugliness. The sight of a beautiful person does not make another so likewise, a blind person does not render another blind. Why then should a deaf person make others so also? Why are we Deaf and Dumb? Is it from the difference of our ears? But our ears are like yours; is it that there may be some infirmity? But they are as well organized as yours. Why then are we Deaf and Dumb? I do not know, as you do not know why there are infirmities in your bodies, nor why there are among the human kind, white, black, red and yellow men. The Deaf and Dumb are everywhere, in Asia, in Africa, as well as in Europe and America. They existed before you spoke of them and before you saw them."
