Side Effects From Cancer Treatment May Not Go Away

There may be a reason you’re finding it hard to resume the life you had.

While cancer treatment can eliminate cancer in the body it can also leave the body changed. Chemotherapy and/or radiation can cause great damage. Too often we’re not told what to expect after treatment has ended.

Late Effects & Lingering Side Effects

There can be lingering or long-term effects from treatment. Lingering effects may persist long after treatment has concluded. Late effects can present themselves months or even years after cancer treatment. Some of these can include:

Dental problems

Chemo can cause problems with tooth enamel. Radiation to the head and neck can cause gum disease. Damaged salivary glands can affect saliva production, causing dry mouth.

Cognitive problems

Chemo can cause thinking and memory problems. This is also known as ‘chemo brain.’ Symptoms can include short term memory problems, difficulty concentrating, confusion, difficulty finding the right word, short attention span, a feeling of mental fogginess, difficulty in remembering conversations, being disorganized, etc.

Numbness, tingling, or pain in hands and/or feet

Also known as neuropathy, nerve injury can be caused by both chemo and radiation and can make movement very painful.

Damage to heart, lungs, or kidneys

Chemo drugs can cause weakening of the heart muscle, also known as congestive heart failure (CHF), leading to shortness of breath, swelling of hands and feet, and dizziness. Radiation to the chest can also cause coronary artery disease.

Early menopause

Cancer treatment can cause women to have menopausal symptoms. Women who have not yet gone through menopause may have worse symptoms than those of a woman who has experience natural menopause. This is due to hormones being reduced very quickly, rather than naturally. Radiation to the pelvic area will most likely cause sterility with the very first session.

Osteoporosis

Chemo can cause thinning of the bones. This can lead to bones that are easily damaged or broken from seemingly mild injuries.

Lymphedema

Radiation can damage lymph nodes leaving lymph fluid unable to properly drain. This can result in fluid building up under the skin and leaving parts of the body swollen. This can develop many years after treatment.

Infertility

Radiation on the pelvic area, in both women and men, can cause damage to the reproductive organs.

Incontinence

Radiation on the pelvic area can cause damage to the pelvic floor muscles. This can result in urinary and/or fecal incontinence.

Erectile dysfunction

Chemo can slow down testosterone production which can lead to a change in sexual desire. Both chemo and radiation can cause damage to the arteries and nerves, leading to an inability to achieve erection.

Vaginal or anal stenosis

Radiation to the pelvic area can cause thickening and scarring of the soft tissue, also known as stenosis. This can cause vaginal canals to tighten and shorten resulting in painful or even impossible intercourse. Anal stenosis can cause painful bowel movements and very narrow stools. Stenosis of the anus can also result in an inability to have anal intercourse.

Soft tissue, bone, and joint problems

Chemo and radiation can cause scar tissue to form in the joints, leading to loss of motion and pain. Radiation on the pelvic area can lead to pain while walking or sitting.

Hearing loss

High doses of chemo can cause ringing in the ears (tinnitus) or damage to hearing. This can occur years after treatment.

PTSD

The diagnosis of cancer and subsequent cancer treatment can be very traumatic. While they are going through treatment the individual is often solely focused on dealing with the immediate symptoms of chemo and radiation. Once treatment is finished the individual can feel overwhelmed with distressful thoughts, fear, shock, trouble sleeping, and feeling alone.

Each person’s Experience Is Unique

Each person’s experience is unique and not everyone will experience the same symptoms. Some people may not have any lingering or late effects at all. Different chemo drugs can cause different symptoms. Individuals who did not receive radiation will be spared some of these effects.

Those who DO experience lasting or late effects may find that the effects can affect quality of life. Side effects can be distressing and difficult to deal with. Sometimes, even the people closest to you don’t understand the toll it takes on you. You may want to talk to your doctor or therapist about ways to manage or cope with your lasting effects.
