Cancer happens when mother to fetus
The possible transmission of cancer from a pregnant mother to her unborn child. As if it were a contagion, small developed exactly the same condition that her mother suffered. However, to date, not been able to demonstrate strong evidence that transfer.
After analyzing the recent case of a girl (which was diagnosed with leukemia during the period of gestation) and small (who developed the disease shortly after birth), the track will look at the genetic mother to child transmission. Through analysis of several achievement demonstrate that cancer cells had the baby were identical to his mother and had the same origin. An examination of blood samples taken to the newborn after delivery indicated that they had malignant cells at birth.
Further evaluations showed that the malignant cells of baby lacked a region of DNA that would identify them as a foreign element from the body’s immune system.
The immunity of the fetus usually destroys any cell that is not theirs. This is one reason why the transmission of cancer is exceptional in this particular case is a type of leukemia that the fetus could not recognize and therefore not detected.
Moreover, in the exceptional case of a cancer cell to pass to the fetus, it does not have the disease. What happened to your daughter is jy woman who have spent many cells
The placental barrier
According to the researchers suggest, this genetic mutation observed in the baby might have made it possible for cancer protection pierce the placenta and escaped the alert system of defenses.
The uniqueness of these cancer transmissions from mother to fetus testify to the effectiveness of the placenta as a barrier. In addition to the immunity of the fetus and its ability to repel agents that are not yours, the placenta has a very important plug not to break through anything. Blood vessels has very effective at separating cells from the mother and fetus.
In fact these are very strange. It’s anecdotal. You’ve never seen such a breast cancer.
