Is taking sheep placenta or stem cell products risky for causing cancer or turning lymph nodes into cancer?

I am 29 years old and I am planning to take sheep placenta capsules by (cell labs) for skin rejuvenating and lighting pigmentation purposes. Knowing that I have lymph nodes in my breast but they are not cancer. I am hesitating as one of the pharmacists said we do not recommend it for people who have cancer in their family history, then when she knew about the lymph nodes, she said I wouldn't recommend it. Any clarifications? *We do not have cancer in the family history.
