At 57 years previous, Margo Wickersham was recognized with stage 1 bladder most cancers. The actual property skilled had no recognized danger components for the illness and recalled being fully wholesome till she noticed just a little little bit of blood in her urine. After receiving the prognosis and whereas looking for remedy, Wickersham discovered she truly had a second, totally different bladder most cancers — a uncommon kind known as plasmacytoid most cancers. Consequently, she needed to have her bladder eliminated fully, an expertise she documented in her e book, Gratitude in the Storm: When Not Dying Is Enough to Keep Fighting.
Whereas plasmacytoid most cancers is rare, bladder most cancers survivors not solely must be careful for recurrence, however all of them too usually face the chance of getting further cancers.
Bladder most cancers is the 10th most common kind of most cancers worldwide, sometimes affecting folks over 55 years previous. Whereas it happens three to 4 occasions extra usually in males, the American Cancer Society estimates that greater than 20,000 American girls will likely be recognized with the illness in 2024.
What’s extra, bladder most cancers survivors have the best charge of getting a second primary cancer. “I’ve seen sufferers who’ve had a number of urological malignancies, or quickly after we deal with them they usually get higher, they get lymphoma,” mentioned Armine Smith, M.D., director of Johns Hopkins Urologic Oncology at Sibley Memorial Hospital.
In one study taking a look at greater than 2 million sufferers, about 8% of all most cancers survivors ended up with a second main most cancers, however 34% of these with bladder most cancers had been recognized with a second main most cancers inside 20 years. Of these, 25% had been recognized with lung cancer, the most typical second main most cancers affecting bladder most cancers survivors.
What are second main cancers?
Second main cancers are fully new cancers that may have an effect on survivors months or years after main cancers. They’re totally different from metastatic cancers, which begin in a single organ and unfold to different organs. “Although the most cancers has moved on to a special organ, it retains the traits of the unique most cancers cells,” Smith mentioned. “The bladder is lined with urothelial most cancers cells, and most bladder cancers are urothelial. If this urothelial most cancers leaves the bladder and goes to lymph nodes, liver, lungs, and so forth., it would retain its urothelial traits.”
Second cancers, in distinction, are unrelated to the first most cancers, so they’re additionally unrelated to relapses or recurrence of the first most cancers.
Along with lung most cancers, a number of the most common second cancers bladder most cancers survivors are at elevated danger for embrace a second (unrelated) bladder most cancers, as in Wickersham’s expertise, or most cancers of the renal pelvis/ureter, kidney, vagina, rectum, pancreas, larynx and esophagus.
“What we don’t know is whether or not it’s actually the bladder most cancers placing folks at larger danger of second most cancers, or if it’s the publicity that led to the bladder most cancers that’s additionally answerable for the second most cancers, or if it’s as a result of we as urologists comply with these sufferers for a really very long time and decide up these varieties of latest diagnoses over time,” Smith mentioned.
Threat components for growing second main most cancers
Whereas scientists don’t know all the explanations bladder most cancers survivors get extra secondary cancers, the reason for the first most cancers could put folks at larger danger for added cancers.
“As a result of bladder most cancers is taken into account to be an exposure-related most cancers, there are some issues that may have an effect on the person’s danger for growing different cancers which may be associated to that publicity,” Smith defined.
Smoking is the largest danger issue. Publicity to different carcinogens, together with dyes reminiscent of these used within the textile, paint, and salon industries (assume: hair dye), and chemical substances used within the auto business, additionally places folks in danger. However some, like Wickersham, can nonetheless get bladder most cancers and second cancers regardless of having no recognized exposures to tobacco or different chemical substances.
Moreover, Smith says, genetic mutations reminiscent of these in folks with Lynch syndrome could put a small variety of sufferers prone to growing a number of cancers.
“Although bladder most cancers will not be a genetic one, there are some genes that put folks in danger for growing bladder or urothelial most cancers,” Smith mentioned. “And people genes may also be related to uterine, colorectal and a few GI malignancies.”
In relation to race, white persons are about twice as seemingly as different teams to get bladder most cancers, however one study discovered that Asian Pacific Islander bladder most cancers survivors have an elevated danger of getting a second most cancers.
The way to scale back danger of a second most cancers
Whereas it’s unimaginable to remove danger, Smith advises following the American Cancer Society screening guidelines in place for lung most cancers, GI cancers and gynecological cancers.
“There are preventive measures folks can take simply to make themselves wholesome total and put them at much less danger of growing quite a lot of malignancies,” she mentioned. “This contains bodily exercise, consuming complete meals, not consuming an excessive amount of pink meat — particularly charred pink meat — limiting alcohol and avoiding tobacco.”
It’s additionally essential to go to healthcare suppliers commonly after present process remedy for bladder most cancers and talk with them about any new signs that may very well be proof of a second most cancers.
