One is old and slow, one is young and fast. Opposite ages, opposite tempos.
Pairing these two makes both stick, because nearly every feature is a mirror image.
| Prostate | Testicular | |
|---|---|---|
| Typical age | Over 65 | 15–35 — young men |
| Tempo | Usually slow-growing | Fast-growing |
| First sign | Often none; urinary changes later | Painless firm lump or heaviness |
| Detected by | PSA and digital rectal exam | Self-examination |
| Spreads to | Bone — pelvis, spine, ribs | Lymph nodes, lungs |
| Outlook | Good when confined | Very high cure rate, even when spread |
Old and slow versus young and fast. If a stem gives you a 25-year-old with a scrotal lump, it is not prostate. If it gives you a 70-year-old with back pain and trouble starting his stream, think prostate with bone metastasis.
Early prostate cancer causes no symptoms at all. When urinary symptoms do appear they are the same ones benign enlargement causes, which is exactly why they get dismissed.
Symptoms, when they come
| BPH — benign | Prostate cancer | |
|---|---|---|
| On rectal exam | Smooth, rubbery, symmetrically enlarged | Hard, irregular, nodular, asymmetric |
| Course | Gradual urinary symptoms | Silent, then urinary or bone symptoms |
| PSA | Can be mildly raised | Often higher, and rising over time |
Treatment and its costs
The most common solid cancer in men aged 15–35, and one of the most curable cancers there is — if it is found. Finding it depends almost entirely on the man noticing it himself.
Signs
Painless again. Young men expect cancer to hurt and wait, and this one does not wait with them.
Risk factors
Normal anatomy that gets mistaken for a lump: the epididymis is a soft, comma-shaped structure along the back of each testis, and one testis normally hangs slightly lower than the other. Say both out loud when teaching, or the man finds his own epididymis and panics — or worse, assumes every lump is normal.
Say the awkward part. These are young men who will not raise body image, sexual function or fertility on their own. Raise it first, matter-of-factly, and the conversation becomes possible.
