Understanding the Signs and Symptoms of Lung Cancer

Understanding the Signs and Symptoms of Lung Cancer

Staff Writer |Feb 14, 2024

Awareness Saves Lives

Lung cancer occurs when cancerous cells form in the lungs. Like other cancers, as the disease develops, tumors are formed. As the disease progresses, it has the potential to spread to other regions of the body.
Lung cancer is an umbrella term referring to several different cancers in the lung, including non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC).

NSCLCs start in lung tissue. It is comprised of three specific diseases: adenocarcinomas, squamous cell carcinomas, and large cell carcinomas. SCLCs are a rarer form, originating in the bronchi.

They are similar in symptoms, diagnosis, treatment, and risk factors. SCLCs tend to be more aggressive than NSCLCs. When cancer is more “aggressive”, it means that the growth of the cancer cells is more rapid. Rapid progression of cancer means that tumors grow faster and spread to other parts of the body more quickly, meaning the time window for “effective” treatment is smaller and the prognosis is poorer than non-aggressive cancers.

Getting a Diagnosis

Anyone can get lung cancer. This is no population of people that have absolute immunity from the disease. That being said, certain groups of people are more likely to contract lung cancer than others.

Generally, lung cancer is found in older people over the age of 65. Some lifestyle choices, such as smoking tobacco, can increase the risk of getting a diagnosis.

Remember, just are there are no populations that are immune to developing cancer, but there are plenty of “at-risk” individuals who will never develop it. This does not mean you should ignore warnings over certain activities, such as smoking, just because you can think of someone who was an exception to the rule.

Early Signs of Lung Cancer

When it comes to cancer, one of the most important things you can do is get an early diagnosis. Early detection will put you in a better position in terms of treatment.

Catching the disease before it gets the chance to travel to other parts of the body will make it easier to treat. If it does not spread, physicians can concentrate treatment techniques on specific areas, which can drastically increase your chances of beating it.

The main problem that makes cancer so deadly is that you often do not notice until it is too late. Oftentimes, the early signs of disease are easy to overlook.

Unfortunately, lung cancer normally does not cause any noticeable symptoms until later on. If you are demographically vulnerable to developing lung cancer, consider paying special attention to these early warning signs:

  • Chronic cough, with no apparent cause.
  • Coughing up blood; you may notice spotting on tissues.
  • Chest, back, or shoulder pain, especially when you take deep breaths or laugh.
  • Inappropriate shortness of breath, which may happen when doing non-strenuous, daily activities that should not cause any breathing problems.
  • Weight and appetite loss, with no apparent cause.
  • Fatigue or feelings of weakness with no known cause.
  • Hoarseness, or having a raspy voice, can be a sign of respiratory problems.
  • Wheezing, even during regular breathing.
  • Chronic bronchitis or pneumonia.

Any persistent respiratory infection should be brought to the attention of your physician. As lung cancer advances, the severity of symptoms will worsen for most patients.

Advanced Symptoms of Lung Cancer

In addition to the symptoms mentioned above, other signs of cancer may manifest after the disease has had time to progress. These symptoms will arise in response to the fact that the disease has entered other parts of the body.

How you experience these symptoms will depend heavily on where the cancer spreads to.

  • Bone pain: Can occur anywhere in the body but likely in the hip or the back.
  • Jaundice: The yellowing of skin and eyes is a sign the liver has been disrupted by something.
  • Disturbances to the nervous system: When cancer spreads to the brain, it can cause many different symptoms. These symptoms can include things such as persistent headaches, fatigue, numbness, lightheadedness, seizures, and sudden problems with balancing.

When to See a Doctor

You should always discuss any major changes in your bodily functions with your doctor. It is impossible to know whether or not something is cancerous until you undergo a medical examination.

More than likely, these symptoms are not cancer. This does not mean that you should ignore them. Even if a collection of symptoms is not cancer, it can be a sign of another medical condition.

As early intervention is essential for dealing with any cancer, it is important to talk to your doctor as soon as you notice these problems when they become persistent and occur with no explanation.

7 Treatment Options for Schizophrenia

Carlos Mendoza | February 14, 2024

Talk to your Doctor About Treatment for Schizophrenia Effective treatment for schizophrenia requires a combination of approaches tailored to each patient’s specific needs. Medication like Uzedy, therapy and lifestyle changes all play a role in managing symptoms, and help patients lead more stable, fulfilling lives. In this article we’ll look at common treatment options for schizophrenia 1. Antipsychotic Medications The cornerstone of treatment for schizophrenia is antipsychotic medication, like Uzedy. It's designed to reduce symptoms such as hallucinations, delusions and paranoia. Antipsychotics work by targeting neurotransmitters, particularly dopamine, which is often imbalanced in individuals with schizophrenia. They help stabilize thoughts and emotions, allowing people to better engage in daily activities and therapy. Uzedy (Risperidone Extended-Release Injection): Uzedy is a newer, long-acting injectable form of risperidone, which is particularly helpful for patients who struggle with adhering to a daily medication regimen. Given as a monthly or bi-monthly injection, Uzedy provides consistent medication levels, reducing the risk of symptom relapse. This can be particularly valuable for individuals with schizophrenia, as regular medication adherence is essential to symptom stability. Uzedy’s extended-release formulation allows the medication to work over time, reducing fluctuations and helping maintain a stable mood and thought pattern. Typical (first-generation) antipsychotics: These medications, such as haloperidol and chlorpromazine, were the first types of antipsychotics developed and are effective in controlling positive symptoms like hallucinations. However, they often come with side effects, including stiffness, tremors and tardive dyskinesia (involuntary muscle movements). These side effects can be difficult to manage, which has led to the development of newer, second-generation antipsychotics. Atypical (second-generation) antipsychotics: Newer antipsychotics, such as risperidone, olanzapine and aripiprazole, tend to have fewer side effects related to motor functions. They are often preferred because they also address both positive and negative symptoms of schizophrenia, such as emotional flatness or withdrawal. Although these medications also come with side effects, such as weight gain and metabolic changes, they are generally better tolerated than first-generation antipsychotics. [youmaylike] 2. Psychotherapy and Cognitive Behavioral Therapy (CBT) Medication is often combined with psychotherapy to improve outcomes. CBT, for example, helps patients recognize and change thought patterns that may contribute to symptoms. Through CBT, patients learn strategies to handle paranoia, manage delusions and cope with hallucinations. Therapy provides tools to differentiate between reality and perceptions shaped by schizophrenia, helping patients achieve a better quality of life. Social skills training and family therapy are also valuable, as they equip patients and their loved ones with coping mechanisms and communication skills. 3. Psychoeducation Education plays a critical role in managing schizophrenia. Psychoeducation programs inform patients and families about the condition, helping them understand symptoms, treatment options and coping strategies. Psychoeducation can include information on identifying early warning signs of relapse, understanding the side effects of medications, and managing daily stressors. Patients who are educated about their condition are often better able to manage symptoms and adhere to their treatment plan. 4. Supportive Housing and Vocational Rehabilitation For many individuals with schizophrenia, maintaining employment and independent living can be challenging. Supportive housing programs provide a structured, safe environment where residents receive assistance with daily activities, medication and social skills. Vocational rehabilitation programs, on the other hand, focus on helping individuals develop skills to find and maintain employment. These programs may offer job training, resume building, and interview preparation. Stable housing and vocational support contribute significantly to improved outcomes, providing a sense of purpose and routine. 5. Lifestyle Modifications and Self-Care While schizophrenia requires medical intervention, lifestyle choices also play a crucial role in managing symptoms. Regular physical activity, a balanced diet and adequate sleep are essential. Exercise can help improve mood, reduce anxiety and manage weight gain, a common side effect of antipsychotic medications. Diet is equally important; reducing sugar and unhealthy fats may help avoid metabolic complications associated with antipsychotic drugs. Additionally, sleep is vital for mental health, and establishing a routine can help improve both mood and cognitive function. 6. Long-Acting Injectable Antipsychotics (LAIs) Long-acting injectables like Uzedy provide an alternative for patients who struggle to take medication consistently. LAIs are administered every few weeks to months, ensuring stable levels of medication and reducing the likelihood of missed doses. LAIs can reduce the frequency of relapses and hospitalization, as they eliminate the need for daily pills. Some other examples include Abilify Maintena, Invega Sustenna and Aristada. For individuals prone to forgetting doses or struggling with self-management, LAIs can provide a more consistent and manageable form of treatment. 7. Electroconvulsive Therapy (ECT) For patients with severe symptoms that don’t respond to medication or therapy, electroconvulsive therapy (ECT) may be considered. ECT involves a brief electrical stimulation of the brain while the patient is under anesthesia, and it’s typically used when other treatments have failed. ECT has been shown to reduce severe symptoms, particularly catatonic symptoms and severe depressive states in patients with schizophrenia. It is usually a last resort and performed under careful medical supervision, but it can provide relief when other methods are ineffective.

5 Ways to Improve Your Quality of Sleep

Cassidy Anthony | February 14, 2024

How to Get Better Sleep Many people struggle with sleep disorders like hypersomnia and narcolepsy. Thankfully, treatment options like Xywav exist to help manage consistent, healthy sleep patterns. In this article we're looking at five different ways on how to get better sleep, and breaking each one down. 1. Prescription Medications for Sleep Disorders Certain medications are specifically designed to help regulate sleep patterns and address various sleep disorders. These options can be helpful for those who have severe insomnia or issues like narcolepsy: Xywav: Known for its role in managing excessive daytime sleepiness in narcolepsy, Xywav has proven effective in promoting restful sleep. It works by helping to regulate the brain's sleep-wake cycle and is especially beneficial for those with disorders causing fragmented sleep. Ambien: Commonly prescribed for short-term insomnia, Ambien assists with falling asleep faster. Lunesta: Lunesta is meant for short-term treatment of insomnia, helping those who struggle to fall and stay asleep. Belsomra: Belsomra works by blocking orexin, a neurotransmitter involved in wakefulness. It’s effective for people who have difficulty staying asleep and often provides a gentle, non-habit-forming solution. 2. Cognitive Behavioral Therapy for Insomnia (CBT-I) Cognitive behavioral therapy for insomnia, also known as CBT-I, is a non-drug approach to addressing chronic insomnia. The therapy involves working with a therapist to address thoughts and behaviors that interfere with sleep. Techniques used in CBT-I include: Sleep restriction therapy: Sleep restriction therapy limits the time spent in bed to create a stronger association between bed and sleep. Stimulus control therapy: Stimulus control therapy involves finding activities that promote a restful mindset in the bedroom, such as avoiding screens before bed and not working in the bedroom. Cognitive restructuring: Cognitive restructuring helps individuals shift thoughts from sleep anxiety to positive associations with bedtime, ultimately leading to a better night of sleep. [youmaylike] 3. Lifestyle Adjustments to Improve Sleep Quality While this might seem simple, adopting healthier sleep habits can play a substantial role in enhancing sleep quality. Some essential tips include: Maintaining a consistent sleep schedule: Going to bed and waking up at the same time daily helps regulate the body’s internal clock, making it easier to fall asleep and wake up naturally. Creating a relaxing bedtime routine: Engaging in calming activities, such as reading or taking a warm bath before bed, can cue the body for sleep. Exercising regularly: Physical activity, especially in the morning or early afternoon, can improve sleep quality. Avoiding stimulants: Steering clear of caffeine, nicotine and big meals in the hours leading up to bedtime can help promote restful sleep. 4. Natural Supplements for Sleep Support For those looking for natural remedies, several supplements have shown promise in promoting better sleep. Some common supplements for sleep support include: Melatonin: Melatonin is a hormone that helps regulate the sleep-wake cycle. Melatonin supplements can be particularly useful for those dealing with jet lag or unpredictable and late work schedules. Valerian root: Known for its calming properties, valerian root is believed to play a hand in reducing anxiety and improving sleep quality. Magnesium: This mineral plays a role in muscle relaxation and nervous system regulation, helping to alleviate sleep disturbances caused by tension and stress. Lavender: Either as an essential oil or supplement, lavender has been shown to reduce anxiety and improve sleep quality, especially when diffused in the bedroom or taken in small doses before bed. 5. Improving Sleep Hygiene Good sleep hygiene can make a world of difference for those struggling with sleep quality. Sleep hygiene practices include: Limiting screen exposure: The blue light emitted from screens can suppress melatonin production, making it harder to fall asleep. Consider limiting screen time at least an hour before bed. Using blackout curtains: Blocking out light from outside sources creates a darker environment that can help you fall asleep faster and stay asleep through the night. Keeping the bedroom cool: A slightly cool room temperature is optimal for sleep, as it encourages the body’s natural drop in temperature needed for sleep onset.
