When cancer cells enter the lymph or blood system, they can form secondary tumours elsewhere.
<span>Secondary tumours are actually metastasis, cancer that spreads to a different part of the body from where it started. This happens when cancer cells break away from the main tumour and travel via blood or lymphatic system to other certain parts of the body. It is more difficult to treat metastasis because it is not always the same type of an original tumour.</span>

Answered below
Explanation:
Collecting a patient's stem cells and using them for their treatment is known referred to as autologous stem cell transplantation. In autologous stem cell transplantation, stem cells are harvested in the patient's bloodstream or the bone marrow and used to treat or grow organs for the patient.
Using stem cells harvested from your own body is advantageous over stem cells collected from a donor. This is because the case of incompatibility is eliminated. There is also less risk of rejection of organ or graft versus host disorder, where the donor cells attack the host cells thinking they are foreign bodies.
There are fewer side effects and quicker engraftment and therefore quicker recovery.
The sperm cell contribute DNA to the embryo. <span>A sperm contains half of the chromosomes needed for the organism - in humans 23
Also the sperm determines if the embryo will be a male or female. If the sperm contains a Y chromosome with the required SRY gene then the embryo will become a male. BUT if the sperm contains an X chromosome then the embryo will be a female.
