When something is going wrong in your body, there will be signs. They may be subtle, but they are visible in close observation. If you are a smoker, you may be worried about the smell of smoke emanating from your mouth or clothes. However, there are other signs that tell whether you smoke or not and these signs are difficult to get rid of!

Smoking is the harmful act of inhaling tobacco infused smoke and is a common activity all over the world. According to the Center of Disease Control and Prevention (CDC), over 480,000 deaths happen each year due to smoking or smoke inhalation. The organization explained that smoking causes harm to nearly all organs and quitting lowers the risk of early death and other smoking related diseases.

Like many other substances, there are clear tell-tale signs when someone is smoking. This is especially important for finding lung problems like Chronic obstructive pulmonary disease (COPD), which is a lung disease that makes it hard to breathe, sooner so people can get help.

Why Does Smoking Affect Your Physical Appearance?

Action on Smoking and Health (ASH) explains that tobacco smoke has more than 7,000 harmful chemicals like nicotine, carbon monoxide, and various metals like arsenic, cadmium, and lead, quickly reach your lungs and then travel through your blood to all your organs, including your skin. Smoking damages your skin's ability to heal because it increases an enzyme metalloproteinase (MMPs) that breaks down collagen. Collagen is what keeps your skin smooth and elastic. As you lose collagen, your skin sags. Squinting from the smoke and puckering your mouth when smoking also cause wrinkles around your eyes and mouth.

Smoking also reduces blood flow to your skin, which means it gets less oxygen and nutrients. All these things together lead to what doctors call a "smoker's face." Quitting smoking can help prevent or slow down these skin problems."

Visible Signs Of Smoking

Here are some visible signs of smoking in people, according to 2013, Lung India

Fingers and Nails

When people smoke, the tar and other chemicals in the smoke stick to their fingers and nails. This repeated contact causes a yellow stain that's hard to wash off. It's a very common sign that someone regularly handles cigarettes or biris.

Moustaches

Especially in older people with white moustaches, smoking causes a yellowing effect. This is most noticeable in the center of the moustache, where the smoke from the nose directly hits the hair. The consistent exposure to smoke colors the hair over time.

Lips

Heavy smokers often have a bluish-black tint to their lips. This discoloration happens because the chemicals in tobacco smoke affect the blood flow and the color of the skin on the lips. The constant exposure changes the lip's natural color.

Teeth

Smoking causes teeth to stain both inside and out. The outside of the teeth turns yellow from the tar, while the inside develops a brownish-black stain. This happens because the smoke seeps into the enamel and discolors the teeth over time.

Premature Wrinkling

Smoking makes the skin age faster. This leads to wrinkles like "crow's feet" around the eyes and "cobblestone wrinkles" on the neck. This happens because smoking reduces blood flow, limiting oxygen to the skin, and damages collagen, which keeps skin elastic.

Nodular Elastosis

This condition, also known as "Favre–Racouchot syndrome," causes blackheads and wrinkles, especially around the eyes and temples. It is made worse by both sun exposure and heavy smoking. The skin becomes discolored with visible nodules and wrinkles.

Facial Wrinkling and COPD

A study published in Thorax 2006 found a connection between wrinkles on the face and COPD, a lung disease. It's thought that smoking affects both the skin and lungs through similar processes. If doctors notice signs like "crow's feet" on a smoker's face, they might recommend tests for COPD. This early detection can help people get treatment sooner and improve their lung health.

As we brace ourselves for another bout of winter, we can’t help but feel wary about the changes the dip in temperature brings on our mood and mental well-being. You are not imagining winter depression when you start to feel sudden loss of joy.

Seasonal depression is more than feeling gloomy. You may no longer enjoy the activities you once relished, like listening to music, exercising or meeting friends. This isn’t just another effect of winter. Experts have designated a term for it: anhedonia.

Anhedonia refers to the loss of pleasure or interest in something you once enjoyed. It is one of the symptoms of depression, including seasonal affective disorder (SAD). Unlike sadness, anhedonia can render someone feeling disconnected with or indifferent towards things they once enjoyed.

A person experiencing anhedonia may still participate in activities they enjoy but will no longer reap emotional rewards from it.

“Anhedonia is not the kind of sadness where you’re feeling down but still have moments of enjoyment,” Dr Deeksha Kalra, Associate Consultant, Psychiatry, Artemis Hospital, Gurugram, explained to HealthandMe.

Dr Samant Darshi, Consultant Psychiatrist and Neuromodulation Expert at Yatharth Hospitals, told us, “While sadness entails the state of feeling unhappy about something, anhedonia pertains to the lack of enjoyment.”

Dr Kalra said, during SAD, anhedonia may be experienced during the affected season like winter.

“This can happen at the same time as low mood, but it can also be one of the clearest symptoms. In SAD, these changes are usually present during the affected season and resolve with the resolution of the depressive episode. So anhedonia is about muted pleasure, not just feeling sad,” Dr Kalra explains.

Effects Of Winter On Pleasure And Motivation

Changes that come with SAD, a type of depressive phase, usually pertains to specific seasons, like mostly winter. Due to less duration of daylight, the body’s internal clock, known as circadian rhythm, may get affected. Along with circadian rhythm, poor diet, irregular sleep pattern and limited physical activity can also contribute to SAD.

This could cause one to feel difficult to initiative activities they enjoy as they no longer feel motivated, affecting the brain reward system.

“Seasonal affective disorder (SAD) causes disturbance of mood, sleep, energy, and motivation. Activities which were pleasurable before become less rewarding because of this. The changes in daylight hours may affect the body clock or the physiological processes related to mood control. The decrease in energy and motivation makes doing the activity even harder and less pleasurable,” said Dr Darshi.

Dr Kalra explains that there are a lot of phases to experiencing ‘enjoyment’. It involves identifying something rewarding, anticipating it, experiencing pleasure and learning from the experience. Depression can affect all these phases, making previously enjoyable activities feel less rewarding.

“Brain networks including the striatum and nucleus accumbens, contribute to the valuation of rewarding experiences and the motivation of behavior. When their responses are dulled and something that was once naturally rewarding may not have the same emotional resonance,” she says.

Dopamine’s Role In SAD

Dopamine is a neurotransmitter in the brain responsible for motivation, rewards, learning, and directing behaviour as per goals. When we talk about SAD and anhedonia, dopamine comes into the picture as it is related to motivation and rewards.

Dr Kalra explained, “Dopamine is involved in motivation, reward anticipation, learning and determining the value of pursuing something. That’s why dopamine has been looked at when researchers have investigated anhedonia and low motivation.”

But doctors say that anhedonia is not characterised by shortage of dopamine. According to research, SAD has been reported to affect dopamine signalling, including lower dopamine transporter availability in the striatum during symptomatic depression.

Dr Darshi also emphasises that dopamine is only a part of the process.

He said, “Studies concerning depression and anhedonia indicate that changes in the activity of dopamine result in the decrease in motivation and reward sensitivity. However, anhedonia encompasses many brain processes.”

SAD And Anticipatory Pleasure

Anhedonia makes one indifferent by directly affecting the anticipatory pleasure mechanism. Anticipatory pleasure is the excitement one feels before an event. Consummatory pleasure is the enjoyment experienced while the event is in progress.

“Anhedonia can affect the anticipatory pleasure you feel when you look forward to something and the consummatory pleasure you experience when it actually happens. Someone might know that a favorite meal, holiday or meeting with friends should be enjoyable but feel little excitement beforehand. The pleasure might also feel weaker than expected when the event happens,” Dr Kalra explains.

Not Everyone May Experience Same SAD Symptoms

Everyone with SAD experiences anhedonia in different ways. While some may lose interest and pleasure, others may withdraw socially, sleep excessively, eat more, feeling more tired among other symptoms.

“SAD doesn’t affect everybody in exactly the same way any more than depression is a single biological process. Different people can experience different combinations of changes in mood regulation, circadian rhythms, sleep, appetite and energy and reward processing,” says Dr Kalra.

She also said that multiple symptoms may interact. For example, poor sleep could result into daytime sluggishness, making energetic activities less tempting.

Dr Darshi explained, “Individuals with SAD have different presentations since biology, genetics, circadian rhythm, and psychology are unique for each person. Some individuals have disturbances in reward and motivation, whereas others have sleep disturbances or carbohydrate cravings, or even fatigue. Symptoms might be overlapping and are a reflection of various underlying mechanisms.”

Female breast cancer was the most commonly diagnosed cancer among women in India in 2024, with an estimated 237,231 new cases and 96,100 deaths, according to the International Agency for Research on Cancer (IARC).

Despite the importance of early detection, screening uptake remains low. Experts say India needs better access to screening and approaches tailored to age, breast density and individual risk.

Dr. Sandeep Nayak, Chairman of Oncology at MACS-Renova Oncology Institute, KIMS Hospital, Bengaluru, told HealthandMe that population-wide screening remains a distant goal, with opportunistic screening still the norm.

“Because of this, applying blanket Western guidelines is ineffective. We need a pragmatic, age-stratified approach to imaging: utilizing breast ultrasound (USG) for women aged 35 to 45—where dense breast tissue severely limits mammogram sensitivity—and reserving routine mammography for women above 50, where tissue density decreases and diagnostic yield peaks,” he said.

“The alarming epidemiological paradox is that while our incidence is a third of Western nations, our death rate already surpasses theirs. The issue is not that this cancer has an aggressive biology in India; it is the timeline of discovery,” said Dr. Navin Gnanasekaran, Head of Clinical Services, Radiology and Interventional Radiology for the Apollo Group Chennai Region.

Dr. Gnanasekaran said more than 60% of breast cancers in the United States are diagnosed while still localized, with five-year survival exceeding 90%. In India, many cases are detected after the cancer has spread beyond the breast, contributing to a five-year survival rate of 66.4%, he said.

India introduced population-based screening for common noncommunicable diseases in 2016 under the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS), launched in 2010. The program includes breast cancer screening among women aged 30 and above.

However, National Family Health Survey-5 (NFHS-5) data show that only 0.9% of women aged 30–49 had ever undergone a breast examination for cancer detection. Dr. Gnanasekaran placed the median age of breast cancer onset in India at around 45.

Should Mammograms Start at 40—or Later?

Experts differ when routine mammography should begin and whether breast density should influence imaging choices.

Dr. Gnanasekaran recommended digital mammography every two years for women aged 40–60. He proposed linking screening reminders to Ayushman Bharat Health Account (ABHA) IDs, deploying mobile mammography units in rural areas and using validated artificial intelligence (AI) to help interpret scans.

Dr. Nayak recommended ultrasound for women aged 35–45 and routine mammography for those above 50.

Dense breast tissue can make some cancers harder to detect on mammograms. Women at high genetic risk, including those with BRCA mutations or a strong family history, may need earlier surveillance, potentially including contrast-enhanced breast MRI in their late 20s or early 30s, depending on individual risk.

Dr. Gnanasekaran stressed that screening must be supported by accessible diagnostic and treatment services, including timely biopsies.

Is Mammography Safe, and Can It Miss Cancer?

Mammography can miss some cancers, particularly in women with dense breasts. Ultrasound may be added for dense breasts or specific concerns, while MRI is generally used for women at higher risk or in selected situations.

Dr. Garvit Chitkara, Associate Director of Breast Surgical Oncology and Oncoplasty at Nanavati Max Institute of Cancer Care, Mumbai, said the radiation risk from mammography is low, while false-positive results can lead to additional tests.

“At the recommended intervals, mammography does not meaningfully raise your cancer risk. The more real downsides are occasional false alarms that lead to extra tests, which is a reason to have it done at a good centre and discuss any call-back with your doctor,” he told HealthandMe.

A normal mammogram should not be used to dismiss a persistent lump or other breast symptoms. Women experiencing changes should seek medical evaluation even if their most recent screening result was normal.

Which Breast Changes Should You Never Ignore?

Many breast lumps are benign, including cysts and fibroadenomas, but touch alone cannot reliably distinguish a harmless lump from cancer.

“Any new lump, or a lump that is changing in size or feel, should be examined by a doctor. A quick check usually settles it and gives you peace of mind,” Dr. Chitkara said.

Persistent redness, itching or skin thickening, breast dimpling, puckering, an orange-peel texture, nipple retraction or unusual nipple discharge should also be evaluated.

Early breast cancer is often painless. Women should not wait for pain before seeking medical attention.

Molly, a head nurse at a leading city hospital, was diagnosed with breast cancer. Chemotherapy and surgery helped her overcome the disease, but 26 years later, it resurfaced during a routine examination. By then, the experience had faded from the minds of many, including her family.

Molly is not alone. Filmmaker and author Tahira Kashyap was diagnosed with Stage 0 breast cancer, or ductal carcinoma in situ (DCIS), in 2018. She underwent a mastectomy, followed by systemic therapies and chemotherapy. In 2025, she revealed that her cancer had relapsed after seven years.

“Round 2 for me... I still got this,” she wrote, emphasizing the importance of routine screening and regular mammograms.

In 2024, breast cancer caused an estimated 694,000 deaths and 2.4 million new cases worldwide, making it the most commonly diagnosed cancer among women in 164 of 186 countries.

“The last chemotherapy session or final radiation appointment may mark the end of active breast cancer treatment. But for many women, the fear does not end there. ‘What if the cancer comes back?’ can remain an unsettling companion, even on the happiest days,”

Prof. Jyoti Bajpai, Director – Medical, Precision & Immuno-Oncology, Apollo Hospitals, Mumbai & Western Zone, told HealthandMe.

Despite advances in screening and treatment, completing treatment does not mean an immediate return to normal life. As hospital visits become less frequent, friends and family may assume the hardships are over. But survivorship can mark the beginning of a quieter struggle with fear, uncertainty and adapting to a changed body and mind, added Dr. Randeep Singh, Director and Senior Consultant, Oncology Services, Medical Oncology, Haemato-Oncology & BMT, Narayana Hospital, Gurugram.

The Physical and Financial Burden of Survivorship

Fatigue, joint pain, menopausal symptoms and changes in body image may persist after treatment, Prof. Jyoti noted. Every ache can trigger anxiety, while follow-up appointments can revive old fears.

Restrictive diets, conflicting advice and misinformation can complicate everyday decisions. The pressure to resume family and professional responsibilities may also leave little room for emotional distress.

An Indian study led by the Kidwai Memorial Institute of Oncology in Karnataka and presented at the 2026 ASCO Annual Meeting found that 43% of breast cancer survivors reported persistent fatigue and reduced physical activity, while 71% reported financial concerns.

The Fear of Recurrence

Dr. Randeep described fear of recurrence as one of the most challenging aspects of survivorship.

“Fear of recurrence is one of the most challenging aspects of survivorship. Survivors still may be concerned about the bumps, aches, and pains they experience that are different from those they are used to. You may start to think of things that cause you fear and anxiety: How can it be that I just have a headache, but how can it be that the cancer has returned?”

Scans, blood tests and follow-up visits can also be emotionally draining.

“There may be worry or stress that is hard to describe to someone who's never been through it before. To a survivor, it can be a reminder of all the things that have happened to her and all the things she fears. This worry is not a weakness. The journey from cancer survivor can alter someone's notion of safety, health and the future.”

Changes in Body Image and Intimacy

Changes in appearance can affect self-confidence, Dr. Randeep told HealthandMe. Hair may regrow differently, scars may remain, and the loss or reshaping of a breast can change how a woman feels about her body. Physical discomfort, diminished libido or reduced attraction to a partner may also affect intimacy.

“These experiences are so personal. A woman may be thankful to be alive and at the same time mourn the body, energy, or normalcy she had prior to her cancer diagnosis. Both emotions can be experienced at the same time and neither lessens her strength,” he said.

The Loneliness Behind the Smile

During treatment, support may come through phone calls, hospital visits, meals and messages of encouragement. Once treatment ends, that attention can fade as people assume the survivor is fine.

Survivors may also feel pressured to remain positive, particularly when others remind them how fortunate they are to have survived. They may suppress anxiety, sadness or frustration to avoid worrying their families.

Why Support Must Continue After Treatment

Cancer care must extend beyond controlling the disease, said Prof. Jyoti Bajpai, Founder & President-Elect of the Immuno-Oncology Society of India (I-OSI) and Asia Co-Chair of the Society for Immunotherapy of Cancer (SITC).

Alongside appropriate surveillance and management of physical symptoms, women need evidence-based guidance, nutritional support and psychological care. Families must recognize that recovery is individual and that fear of recurrence deserves compassion, not dismissal.

Family and friends, counsellors and breast cancer survivor groups can provide emotional support. Healthy habits, gentle physical activity, adequate rest and honest conversations with healthcare professionals can also help survivors cope. Persistent anxiety, depression or physical symptoms should not be ignored; medical or psychological help should be sought when needed.

Survivorship is a process of rebuilding trust, finding happiness and accepting an uncertain future. The goal is not merely to help women live beyond cancer, but to give them the support, understanding and confidence to live fully again.

“No woman should have to navigate that journey alone,” Dr. Jyoti said.
