Yes, rare cancers are generally harder to treat due to late diagnosis (no screening, vague symptoms), fewer treatment options (less research/data), lack of established guidelines, difficulty finding expert doctors, and challenges accessing new drugs. These factors often mean patients face longer diagnostic delays, less information, and more complex care journeys, though there's hope through advocacy and research.
Incurable cancers are those that current treatments cannot completely eliminate, often because they are advanced (spread) or have returned after initial treatment, but they are not necessarily untreatable; treatments like chemo, radiation, and new targeted therapies aim to control the disease, slow growth, relieve symptoms, and improve quality of life. Common examples of cancers often considered incurable include pancreatic, liver, brain, esophageal, and certain advanced lung cancers, but research continuously offers new hope, with many patients living longer with ongoing management.
Many factors make a rare cancer harder to treat. It can take a long time to diagnose. It's hard to find a doctor who knows a lot about a particular rare cancer and how to treat it.
Because of chemotherapy's considerable side effects, it may not be safe for individuals who have underlying conditions. If your oncologist worries that your body is not strong enough to withstand chemotherapy, they will likely recommend other treatment options.
Over the last 40 years, research has made astonishing progress and survival rates for many cancers have increased dramatically over the last decades.
About 90% of cancers are caused by environmental and lifestyle factors, not genetics, including smoking, poor diet (red meat, fried foods), alcohol, sun exposure, pollutants, infections, obesity, and inactivity; only 5–10% are due to inherited genetic defects, with most cancers arising from lifestyle-induced genetic mutations. Tobacco alone accounts for about a third of cancer deaths, while diet, obesity, and inactivity contribute significantly, with controllable factors being key to prevention.
Every cancer is caused by a build-up of mutations and, as the cancer progresses, more and more different mutations accumulate. This means two people with the same broad type of cancer can carry individual sets of mutations. This means a drug that works for one cancer patient might have absolutely no effect for another.
Doesn't the benefit of chemotherapy decrease with age? In most cases, it does not. A healthy older person often has the same chances of responding to treatment or being cured than a younger one.
Immunotherapy, a newer type of cancer treatment, uses IV infusions of medication to rev up the patient's own immune system. Immunotherapy treatments can work across different cancer types and may be effective in treating even advanced and hard-to-treat cancers.
When is it time to think about stopping cancer treatment? If you have had three different treatments and your cancer has grown or spread, more treatment usually will not help you feel better or increase your chance of living longer.
Patients with rare cancers face delays in diagnosis, leading to late-stage presentation. Clinical research, diagnosis and treatment access for rare cancer patients require a boost. Lack of R&D funding and regulatory hurdles complicate access to precision oncology drugs.
Rare cancers are those that affect fewer than 40,000 people per year in the U.S. As a group, they make up just over a quarter of all cancers. Because rates of cancer in children are very low, all children's cancers are considered rare. A quarter of all cancer deaths each year are due to rare cancers.
Primary tumors in the following locations are associated with a relatively high prevalence of pain:
Your oncologist takes information about cancer survival rates into account when thinking about your prognosis. But they consider much more than data: They consider everything that they know about you, from the type of cancer that you have and the cancer stage to your age and overall health.
Many ask, “what cancers don't cause death? Thyroid, testicular, and some skin cancers often have very high survival rates and rarely lead to death.
Make sure that you have a good support network of positive people around you, such as close friends and family, doctors and nurses, or a counsellor. These people can help lift your spirits and be there when you need a shoulder to cry on or an ear to listen to how you feel.
Oral chemotherapy is a cancer-fighting drug given by mouth in tablet, capsule, or liquid form. It is prescribed by your doctor, nurse practitioner, or physician's assistant, and has the same benefits and risks as chemotherapy given by infusion. Today, many cancer patients receive oral chemotherapy as a treatment.
While chemotherapy offers around a 30% success rate, targeted therapy is successful in up to 80% of cases. Unlike the scatter-gun chemotherapy approach, targeted therapy is considered more sniper-like, accurately taking out its target without any collateral damage to otherwise healthy cells.
Age was of less importance, with patients aged 70–79 years versus those aged ≥80 years. Treatment of elderly NSCLC patients with chemotherapy is feasible if they have a good PS and appears to prolong survival. In this study, we found no significant differences in survival either between age groups or genders.
The oncologist may plan to administer chemotherapy in cycles of 1–5 days each, with 2 days off, for a total of 7 days (7-day rule chemotherapy), or continuously for 1–5 days per session and rest for 3–4 weeks to allow the white blood cells and the body to recover and be ready for the next session.
You might have physical changes like hair loss, skin changes or new scars, ostomies, weight changes, or loss of limbs. Cancer and treatment might also cause changes to your sex organs, sexual health, fertility, or mental health. Some of the changes may be temporary, while others are permanent.
Resistance can occur when cancer cells—even a small group of cells within a tumor—contain molecular changes that make them insensitive to a particular drug before treatment even begins. Because cancer cells within the same tumor often have a variety of molecular changes, this so-called intrinsic resistance is common.
Some cancers become resistant to treatment more quickly, others are in harder to reach places. Some cancers can grow more quickly, and spread more easily than others. All of these things can make it some cancers harder to treat. Cancer research helps us to understand how these cancers grow, and spread.
A cancer diagnosis is never good news, but there are five types that are are particularly deadly: pancreatic, ovarian, lung, glioblastoma and triple-negative breast. These cancers are often diagnosed late, can be difficult to remove surgically and rebuff most therapies.
