When one partner is living with the side effects of cancer treatment, both people may feel the impact.

The patient may be coping with discomfort, fatigue, uncertainty, and changes in desire. Their partner may feel rejected, worried, helpless, or afraid to initiate affection. Even in strong relationships, these experiences can create misunderstandings.

A partner might think, “They don’t want me anymore,” while the patient is thinking, “I want to feel close, but I don’t recognize my body right now.”

Neither person may know how to start the conversation.

When affection becomes misunderstood

One common challenge is that physical affection can begin to feel complicated. A kiss or cuddle may be interpreted as an invitation to have sex, even when the patient only wants closeness. The patient may begin avoiding affection because they do not want to disappoint their partner, while the partner may withdraw because they fear causing discomfort or pressure.

Talking openly about what different types of touch mean can help. Couples can agree that affection does not have to lead to sex and that either person can change their mind at any time.

This allows physical closeness to become enjoyable again rather than a source of anxiety.

When partners have different levels of desire

Hormone therapy may change one person’s libido while their partner’s sexual needs remain the same. This difference can be difficult for both people.

The partner who wants sex may feel guilty for having those needs, while the patient may feel guilty for not wanting sex. Over time, both may become reluctant to discuss the subject.

It is important to recognize that neither person’s feelings automatically make them wrong. The goal is not to pressure the patient into sex or expect the partner to ignore their own feelings. It is to find ways of maintaining connection that respect both people’s boundaries and needs.

Couples may benefit from:

  • Setting aside time to talk about intimacy without expecting sex to follow.
  • Exploring forms of affection and pleasure that feel comfortable.
  • Discussing pain, fatigue, desire, and fears honestly.
  • Seeking couples counseling or a certified sex therapist with experience in cancer-related concerns.
  • Remembering that intimacy can change over time without disappearing entirely.

Professional counseling can be particularly helpful when communication has become strained or when sexual changes are affecting the relationship.

Alternative treatments and supportive strategies for long-term use

The good news is that patients do not necessarily have to choose between enduring difficult side effects and giving up an important cancer treatment. There are ways to manage many symptoms, although the most appropriate approach depends on the medication, the cancer type, the patient’s medical history, and the severity of the symptoms.

Some strategies involve medication adjustments supervised by the oncology team. Others involve nonhormonal treatments, physical therapy, counseling, or practical changes at home.

1. Nonhormonal options for vaginal dryness and discomfort

Vaginal moisturizers

Vaginal moisturizers are used regularly, rather than only during sexual activity, to help relieve dryness and irritation. Depending on the product and individual needs, they may be used several times a week. Fragrance-free products intended for vaginal use are generally preferable to scented lotions or products containing irritating ingredients.

Personal lubricants

Water-based or silicone-based lubricants can reduce friction during sexual activity and make touch more comfortable. Some people find that silicone-based products last longer. Avoid products that cause burning or irritation, and check compatibility with condoms or other barriers.

Pelvic floor physical therapy

A trained pelvic health physical therapist can assess muscle tension, pain, and difficulty with penetration. Treatment may include relaxation techniques, breathing, gentle movement, and individualized exercises. Strengthening exercises are not appropriate for every problem; some patients need help relaxing overactive muscles instead.

For patients with persistent vaginal or vulvar symptoms, clinicians may discuss additional treatments, including prescription therapies or vaginal dilators when appropriate. Dilators should be used with guidance if pain, scarring, or tissue changes are present.

Low-dose vaginal estrogen may be an option for some cancer survivors, but it is not automatically safe for everyone. Patients with estrogen-sensitive breast cancer, particularly those taking aromatase inhibitors, should discuss the potential benefits and risks with their oncologist and a gynecologic clinician before using it. Other hormone-based products, including vaginal DHEA or testosterone, also require individualized review.

2. Treatments for erectile dysfunction

For patients experiencing erection difficulties, a urologist or sexual medicine specialist may recommend one or more of the following:

  • Prescription medication: Drugs such as sildenafil or tadalafil can help some people achieve or maintain erections when appropriate.
  • Vacuum erection devices: These devices help draw blood into the penis and may be useful for some patients.
  • Penile injections or urethral treatments: These can be considered when oral medication is ineffective or unsuitable.
  • Penile implants: For selected patients with persistent erectile dysfunction, an implant may be a longer-term option.
  • Sexual rehabilitation: A specialist can help patients adjust to changes in arousal, erections, orgasm, and sexual expectations.

These options address different aspects of sexual function. For example, a treatment that helps with erections may not restore libido or resolve relationship concerns. Combining physical treatment with counseling or sexual rehabilitation may be more helpful than focusing on erections alone.

3. Managing hot flashes and night sweats without adding hormones

Hot flashes and night sweats can disrupt sleep and make daily life uncomfortable. Depending on the patient’s cancer treatment and medical history, a clinician may recommend nonhormonal medications.

Options sometimes used for hot flashes include certain antidepressants, gabapentin, and other prescription treatments. Cognitive behavioral therapy and clinical hypnosis may also help some people manage symptoms or reduce their impact.

Not every medication is suitable for every patient. For example, certain antidepressants can interfere with tamoxifen metabolism, so medication selection should be reviewed carefully by the prescribing clinician or oncology pharmacist. Patients should not start or stop medication based on general information alone.

Practical measures may also help:

  • Keep the bedroom cool and use breathable bedding.
  • Dress in removable layers.
  • Keep water and a fan nearby.
  • Track triggers such as warm rooms, spicy foods, or alcohol if they seem to worsen symptoms.
  • Discuss frequent night sweats and persistent sleep disruption with the care team.

4. Exercise and movement

Regular physical activity can support physical and emotional health during long-term hormone therapy. Depending on the individual’s abilities and medical circumstances, walking, resistance training, stretching, swimming, or other enjoyable activities may help reduce fatigue, preserve strength, support bone health, and improve mood.

Exercise may also help address some metabolic effects of androgen-deprivation therapy, including loss of muscle mass and increased body fat.

A gradual approach is often more manageable than an ambitious routine. Someone dealing with fatigue or joint pain might begin with short walks or gentle movement and increase activity as tolerated.

Patients with bone metastases, significant osteoporosis, balance problems, or other treatment-related limitations should ask their oncology team or physical therapist which activities are safe.

5. Nutrition, sleep, and everyday symptom management

There is no single diet that reverses the effects of cancer hormone therapy. However, balanced nutrition, adequate protein when appropriate, hydration, regular sleep habits, and support from an oncology dietitian can help patients maintain strength and manage changes in weight or appetite.

For people experiencing insomnia or repeated nighttime waking, cognitive behavioral therapy for insomnia (CBT-I) may be worth discussing with a healthcare professional.

Keeping a symptom journal can also be useful. Record fatigue, sleep, pain, hot flashes, mood, sexual symptoms, and medication timing. Over several weeks, this information may reveal patterns and help the oncology team recommend more targeted strategies.

6. Counseling and mental health support

Counseling is not only for people whose relationships are in crisis or whose depression has become severe. It can provide a place to discuss changes that are difficult to share with family or friends.

Depending on the person’s needs, helpful options include:

  • Individual counseling with a therapist experienced in cancer care.
  • Couples counseling to improve communication and rebuild intimacy.
  • Sex therapy for changes in desire, arousal, pain, orgasm, or sexual confidence.
  • Cancer support groups where patients can connect with others experiencing similar challenges.
  • Oncology social workers who can help with practical, emotional, and financial concerns.
  • Psychiatric assessment when depression, anxiety, or mood symptoms may require medication or specialized treatment.

A partner may be invited to participate if the patient wishes, but patients should also have opportunities to speak privately with their care team.

7. Reviewing the cancer treatment plan

If side effects are significantly affecting quality of life, patients should tell their oncologist rather than assuming nothing can be done.

Depending on the cancer and treatment plan, the clinician may consider switching to another medication, adjusting the treatment schedule, or exploring other evidence-based approaches. The appropriate choices differ by cancer type and individual circumstances.

Patients should not stop, skip, or change cancer hormone therapy on their own. These treatments can play an important role in preventing recurrence or controlling disease. If side effects are making it difficult to continue, an honest conversation with the oncology team can help identify a safer and more sustainable plan.

Are there natural alternatives to hormone therapy?

This is an important question, especially for patients who feel that the side effects are interfering with their quality of life.

Some people explore acupuncture, mindfulness, yoga, massage, dietary changes, or herbal products in hopes of reducing symptoms. Certain complementary approaches may help with stress, sleep, or symptom management, but they do not replace the cancer-controlling effects of prescribed hormone therapy.

Herbal supplements deserve caution. Products marketed for menopause, libido, testosterone, or hormone balance may contain ingredients that interact with cancer medications or affect hormone-sensitive tissues. Even products labeled natural are not necessarily safe during treatment. Patients should review supplements with their oncologist or oncology pharmacist before taking them.

It is also worth remembering that nonhormonal does not mean ineffective. There are prescription and nonprescription options for many treatment-related symptoms, including hot flashes, sleep disturbances, vaginal dryness, erectile dysfunction, and emotional distress.

The best approach is often a combination of evidence-based medical care and supportive strategies tailored to the individual.

When should patients seek additional medical help?

Patients should contact their healthcare team when side effects begin affecting sleep, daily responsibilities, relationships, emotional well-being, or the ability to continue treatment.

Some concerns deserve prompt assessment rather than waiting for a routine appointment.

  • Persistent depression or anxiety: Seek professional help when symptoms interfere with daily functioning. Thoughts of self-harm or suicide require immediate support through emergency services or the 988 Suicide & Crisis Lifeline in the United States.
  • New or worsening sexual pain: Persistent pain, genital sores, unusual discharge, or bleeding should be assessed by a clinician.
  • Sudden or severe physical symptoms: Chest pain, sudden shortness of breath, fainting, or one-sided leg swelling require urgent medical evaluation, particularly because some cancer treatments can increase the risk of blood clots.
  • Side effects that threaten treatment adherence: Contact the oncology team before skipping or stopping medication. The team may be able to address the problem or discuss appropriate alternatives.

Patients should never feel that they must wait until a side effect becomes unbearable before asking for help.

Questions to ask your oncology team

It can be difficult to remember everything during an appointment, especially when discussing subjects that feel personal. Writing down questions ahead of time can make these conversations easier.

Here are some useful questions to consider:

  • Which side effects are most likely with my specific medication?
  • Could my medication be contributing to changes in my mood, sleep, libido, or sexual function?
  • Are there nonhormonal treatments that could help?
  • What options are available for vaginal dryness, painful intercourse, or erectile dysfunction?
  • Are there safe options for managing hot flashes and night sweats?
  • Could another medication or treatment schedule reduce my side effects?
  • Would a referral to a sexual health specialist, pelvic floor physical therapist, or mental health professional be appropriate?
  • Are any of my current medications or supplements likely to interact with my cancer treatment?
  • What symptoms should prompt me to call you right away?

Patients can also ask whether their cancer center offers a survivorship program, sexual health clinic, or supportive oncology service.

Living well while receiving long-term hormone therapy

Cancer treatment can create a complicated balance between protecting the future and trying to enjoy the present. Patients may be relieved that a medication is helping control their cancer while simultaneously struggling with the effects it has on their bodies, emotions, and relationships.

Both experiences are valid.

It is possible to appreciate the value of treatment and still grieve changes in sexual function. It is possible to love a partner and have little interest in sex. It is possible to want intimacy but need a different kind of physical connection than before. And it is possible to need professional support even when treatment is going according to plan.

For some people, sexual function improves after treatment changes or ends. For others, certain effects persist and require ongoing management. Recovery is not always predictable, and there is no universal timeline for feeling like oneself again.

What matters is that patients have access to information, appropriate medical care, and compassionate support throughout the process.

Partners also benefit from understanding that intimacy is not solely about sexual performance. Listening without judgment, offering affection without expectations, and discussing changing needs can help preserve closeness during difficult periods.

Most importantly, patients deserve to have their quality of life taken seriously. Sexual health is not a frivolous concern, and emotional well-being is not less important than physical treatment. Both are part of caring for the whole person.

Living with cancer does not mean putting every other part of life on hold. With open communication, individualized symptom management, and the right support, many people can find ways to maintain meaningful relationships, improve comfort, and experience intimacy on terms that work for them.

The goal is not to pretend that nothing has changed. It is to make sure that the changes do not have to be faced alone.
