Germ cell neoplasia in situ is the pre-cancer of testicular germ cell tumours: abnormal fetal-type germ cells sitting inside the seminiferous tubules, which will become seminoma or non-seminoma if left. It is found beside almost every testicular cancer and sometimes on its own in the other testis, where low-dose radiotherapy or surgery prevents a second cancer. Below, week by week, is what OnCo's record of Germ cell neoplasia in situ (GCNIS) says about the first two months: the order is typical, the timing is yours to ask about. Sections appear only where the record has something to say. Orientation, not medical advice.
Staging tests establish exactly what and where the cancer is. Everything else follows from the answers.
Ask which of these were tested and what the results were; see the report reader for what each value means.
These specialties appear in the standard of care for this cancer. In most centres they meet weekly as a tumour board to agree each plan; you can ask when yours was discussed and what was decided.
A second opinion from a centre that treats many similar cases is normal, not rude; the standard of care tells you what to compare it against.
Each row is a setting from the standard of care, in the order it usually arises. Not all will apply to you; your stage and biomarkers decide which do. The guideline grade, where recorded, says how strong the evidence is.
Low-dose testicular radiotherapy, orchidectomy, or surveillance in men wanting children; the invasive tumour that follows is treated as seminoma or non-seminoma.

Much of what helps in the first weeks is free if you know to ask: testing, helplines, rides and lodging, second opinions, trial travel.
