Bladder cancer

The treatment plan is not made by one person alone but in a round of surgery, oncology, radiology, pathology and radiotherapy. You may ask what was discussed there and which alternatives came up.

Before a big decision it is planned for in many clinics, and the records belong to you. It costs one to two weeks — acceptable in almost every course, and one asks about that if it is urgent.

It is today part of the treatment and not its opposite: it lessens the exhaustion, keeps muscle and bone and improves how the treatment is tolerated. Begin with guidance, less on bad days, but not nothing at all.

Unintended weight loss worsens how any treatment is tolerated. Restrictive diets do more harm than good here — with loss of appetite, dietary advice helps early, not only once kilos are already gone.

By the clock rather than as needed works better and needs less overall. Fear of dependence is the wrong adviser in this situation — untreated pain costs sleep, appetite and strength.

Psycho-oncological support, social advice for insurance and work, and the question of who takes on what at home. This is no emergency measure but belongs at the start — and the relatives belong in it.

Decades of egg-laying in the bladder wall is one of the main causes in parts of Africa and the Middle East. Anyone who swam there is tested even without complaints.

In superficial bladder cancer the tumour is removed through the urethra; then BCG is put into the bladder — a weakened vaccine that stimulates the immune system in the bladder wall. It is one of the oldest immunotherapies of all and lowers the return distinctly; it runs over one to three years at fixed intervals. Stopping smoking lowers the return measurably, even after the diagnosis. Check cystoscopies stay part of the path, because this cancer often comes back.

In about eight out of ten cases, painless blood in the urine is the first sign. Around three quarters are superficial at diagnosis. After removal it returns in about half within five years — hence the check cystoscopies: every three months at first, then at wider intervals over years. Smoking is the strongest factor, and stopping lowers the return measurably even after the diagnosis.

That is the leading sign: visibly reddish urine that appears once and disappears again, without burning and without fever. Precisely because it stops by itself it often goes unreported.

Frequent urgency, burning and a feeling of incomplete emptying that stays unchanged after two courses and where the urine culture shows nothing.

Smoking is the strongest single link. Added to it are occupational contacts with certain dyes in chemistry, rubber, painting and hairdressing — that belongs mentioned, because it shapes the workup.

A one-sided dull pain in the flank can come from a blocked ureter. Swollen legs and pelvic pain are later signs.

Blood that is visible or only detectable by test, without pain, is the most important sign. It belongs investigated even if it appeared once and vanished by itself.

Blood lost unnoticed through the urine over a longer time leads to anaemia. It explains tiredness that is otherwise put down to age.

Belongs alongside because a tumour at the ureteric opening can obstruct drainage — and because kidney function co-determines the choice of treatment.

Falls before the haemoglobin and shows the silent loss earlier.

The loss of muscle mass helps decide how well a treatment is tolerated. Enough protein spread across the day, together with movement, is the part one holds oneself.

Low values are common with a longer illness, and correcting them counts for bone and muscle. For high-dose courses against the illness itself there are no studies; they can interfere with treatment.

Belong in the workup of an anaemia that is otherwise too quickly put down to the illness or the treatment. Both are easy to measure and easy to supplement.

Nausea, diarrhoea and fever dry one out quickly, and several treatments strain the kidney. Drinking enough is no side issue here.

With a bladder instillation treatment using BCG a live organism sits in the bladder. Live organisms in capsules on top make no sense during that time; outside the instillation phase nothing speaks against them.

After instillation treatments the bladder often burns for weeks, and that is easily taken for an infection. Cranberry does not help against this irritation — it acts on bacteria sticking, and here nothing is sticking.

Measured and replaced by finding. An influence on the course of the illness is not shown; the reason stays bone and muscle.

Clearly worthwhile and well supported when deficient — vegan, older adults, certain drugs. No energy boost without a deficiency.

One diabetes medicine was under suspicion for years of raising the risk; the large follow-up studies found no clear link. By far the biggest influence remains smoking.

Men fall ill three to four times more often, but women are diagnosed later — in them blood in the urine is more often taken for a bladder infection first. That is the practically important point of this difference.

The more dilute the urine, the shorter harmful substances act on the bladder wall. In cohorts higher fluid intake is linked with fewer cases — 1.5–2 litres a day is the usual range.

The claim usually rests on the PET scan: weakly radioactive glucose is injected, and the tumour lights up. That shows tumour cells take up sugar faster than the tissue next to them — not that eaten sugar feeds them. You come to a PET scan fasting, and the tumour lights up anyway; the body keeps blood sugar within narrow limits by itself. It cannot be starved out this way. There is an established link nonetheless, but it runs through body fat: in 2016 the International Agency for Research on Cancer (IARC) reviewed the available studies and found sufficient evidence, for thirteen cancers, that absence of excess weight lowers the risk. That concerns prevention — it is not an answer to where an existing illness came from.

Smoking is by far the biggest factor — stopping is worthwhile after diagnosis too, because it lowers the risk of recurrence. Higher fluid intake is linked with fewer cases in cohorts.
